| 1 | HRM: H-tree based reconfiguration mechanism in reconfigurable homogeneous PE array显示文摘In order to accommodate the variety of algorithms with different performance in specific application and improve power efficiency,reconfigurable architecture has become an effective methodology in academia and industry.However,existing architectures suffer from performance bottleneck due to slow updating of contexts and inadequate flexibility.This paper presents an H-tree based reconfiguration mechanism(HRM)with Huffman-coding-like and mask addressing method in a homogeneous processing element(PE)array,which supports both programmable and data-driven modes.The proposed HRM can transfer reconfiguration instructions/contexts to a particular PE or associated PEs simultaneously in one clock cycle in unicast,multicast and broadcast mode,and shut down the unnecessary PE/PEs according to the current configuration.To verify the correctness and efficiency,we implement it in RTL synthesis and FPGA prototype.Compared to prior works,the experiment results show that the HRM has improved the work frequency by an average of 23.4%,increased the updating speed by 2×,and reduced the area by 36.9%;HRM can also power off the unnecessary PEs which reduced 51%of dynamic power dissipation in certain application configuration.Furthermore,in the data-driven mode,the system frequency can reach 214 MHz,which is 1.68×higher compared with the programmable mode. | Junyong Deng Lin Jiang Yun Zhu Xiaoyan Xie Xinchuang Liu Feilong He Shuang Song L.K.John | 2020 | Journal of Semiconductors2020，41，2： | 4 |
| 2 | Diabolical points in coupled active cavities with quantum emitters显示文摘In single microdisks,embedded active emitters intrinsically affect the cavity modes of the microdisks,resulting in trivial symmetric backscattering and low controllability.Here we demonstrate macroscopic control of the backscattering direction by optimizing the cavity size.The signature of the positive and negative backscattering directions in each single microdisk is confirmed with two strongly coupled microdisks.Furthermore,diabolical points are achieved at the resonance of the two microdisks,which agrees well with theoretical calculations considering the backscattering directions.Diabolical points in active optical structures pave the way for an implementation of quantum information processing with geometric phase in quantum photonic networks. | Jingnan Yang Chenjiang Qian Xin Xie Kai Peng Shiyao Wu Feilong Song Sibai Sun Jianchen Dang Yang Yu Shushu Shi Jiongji He Matthew JSteer Iain GThayne Bei-Bei Li Fang Bo Yun-Feng Xiao Zhanchun Zuo Kuijuan Jin Changzhi Gu Xiulai Xu | 2020 | Light(Science & Applications)2020，9，1： | 2 |

| 6 | Anisotropies of the g-factor tensor and diamagnetic coefficient in crystal-phase quantum dots in InP nanowires显示文摘Crystal-phase low-dimensional structures offer great potential for the implementation of photonic devices of interest for quantum information processing.In this context,unveiling the fundamental parameters of the crystal phase structure is of much relevance for several applications.Here,we report on the anisotropy of the g-factor tensor and diamagnetic coefficient in wurtzite/zincblende(WZ/ZB)crystal-phase quantum dots(QDs)realized in single InP nanowires.The WZ and ZB alternating axial sections in the NWs are identified by high-angle annular dark-field scanning transmission electron microscopy.The electron(hole)g-factor tensor and the exciton diamagnetic coefficients in WZ/ZB crystal-phase QDs are determined through micro-photoluminescence measurements at low temperature(4.2 K)with different magnetic field configurations,and rationalized by invoking the spin-correlated orbital current model.Our work provides key parameters for band gap engineering and spin states control in crystal-phase low-dimensional structures in nanowires. | Shiyao Wu Kai Peng Sergio Battiato Valentina Zannier Andrea Bertoni Guido Goldoni Xin Xie Jingnan Yang Shan Xiao Chenjiang Qian Feilong Song Sibai Sun Jianchen Dang Yang Yu Fabio Beltram Lucia Sorba Ang Li Bei-bei Li Francesco Rossella Xiulai Xu | 2019 | Nano Research2019，12，11： | 1 |

| 8 | Brasenia-inspired hydrogel with sustained and sequential release of BMP and WNT activators for improved bone regeneration显示文摘Although bone morphogenetic protein(BMP) and WNT signaling play pivotal roles in bone development,homeostasis, and regeneration, the applications of proteins to stimulate corresponding signaling pathways showed limited outcomes in the repair and regeneration of bone defects that might be attributed to the reciprocal interventions of these pathways. In order to satisfy the combinational and sequential activation of BMP and WNT pathways, inspired by the heterogeneous hydrogel-liked structures of Brasenia, heterogeneous alginate/chitosan hydrogels were fabricated and spatially loaded with FK506 and BIO to achieve sustained and sequential release of the activators. Alkaline phosphatase staining, alizarin red staining and q RT-PCR results suggested that FK506 and BIO enhanced osteoblastic differentiation in vitro when used separately. Besides, by mixing and matching the activators and the hydrogel layers, a superior releasing mode that a combination of early FK506 release and following BIO release was identified via both in vitro and in vivo explorations for most efficient bone regeneration. These results suggested that drug-loaded heterogeneous hydrogels possess great potentials in treating bone loss defects for future clinical practice. | Xinqing Hao Xuewei Zhang Yue Hu Chunxia Ren Cangwei Liu Lu Wang Yijun Zhou Shuangshuang Wang Huanyu Luo Guangxing Yan Xiao Wang Xiaomeng Wang Feilong Ren Ce Shi, Wenlong Song Hongchen Sun | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
| 9 | Flexible Dry Hydrogel with Lamella-Like Structure Engineered via Dehydration in Poor Solvent显示文摘Hydrogels are among the most promising biologic materials in recent technology with numerous desired applications,including serving as biosensors,drug delivery vehicles,and tissue-engineered products for cell matrices.However,they often dehydrate,and become stiff and brittle in air,causing loss of flexibility and functions.Several layered structures have been proven to increase the strength,toughness,and even flexibility of these materials,which might provide a new clue for the sustenance of the flexibility of drying gels.Herein,we report a novel solvent-dehydrated hydrogel engineering approach,aimed to change the inner structure and keep the flexibility of a dehydrated hydrogel in the air via solvent-induced dehydration,for example,acetonedehydrated polyacrylic acid hydrogel.This flexible dry gel could be folded,twisted,and stretched without any damage due to the assumed lamella-like structures,contrary to dry gels without these microstructures or those with porous structures,which retain brittle consistency.The flexible dry gel also exhibited excellent self-healing capability with the assistance of solvents.Fascinatingly,this flexible gel film displayed strain-visualizing paper writing/erasing performance properties,with water acting as invisible ink.Thus,this fabricated flexible hydrogel film might function as confidential information storage material.Our current approach is versatile,hence applicable to other hydrogels,and provides insight into the engineering of other functional gels for extended future applications. | Feilong Zhang Jiajia Zhou Zhen Gu Man Yang Siheng Li Yongyang Song Jun-Bing Fan Jingxin Meng Peiyi Wu Lei Jiang Shutao Wang | 2020 | CCS Chemistry2020，2，1： | 0 |
| 10 | A review of compact modeling for phase change memory显示文摘Phase change memory(PCM)attracts wide attention for the memory-centric computing and neuromorphic comput-ing.For circuit and system designs,PCM compact models are mandatory and their status are reviewed in this work.Macro mod-els and physics-based models have been proposed in different stages of the PCM technology developments.Compact model-ing of PCM is indeed more complex than the transistor modeling due to their multi-physics nature including electrical,thermal and phase transition dynamics as well as their interactions.Realizations of the PCM operations including threshold switching,set and reset programming in these models are diverse,which also differs from the perspective of circuit simulations.For the purpose of efficient and reliable designs of the PCM technology,open issues and challenges of the compact modeling are also discussed. | Feilong Ding Baokang Peng Xi Li Lining Zhang Runsheng Wang Zhitang Song Ru Huang | 2022 | Journal of Semiconductors2022，43，2： | 0 |
| 11 | Terahertz phononic crystal in plasmonic nanocavity显示文摘Interaction between photons and phonons in cavity optomechanical systems provides a new toolbox for quantum information technologies.A GaAs/AlAs pillar multi-optical mode microcavity optomechanical structure can obtain phonons with ultra-high frequency(~THz).However,the optical field cannot be effectively restricted when the diameter of the GaAs/AlAs pillar microcavity decreases below the diffraction limit of light.Here,we design a system that combines Ag nanocav-ity with GaAs/AlAs phononic superlattices,where phonons with the frequency of 4.2 THz can be confined in a pillar with~4 nm diameter.The Q_(c)/V reaches 0.22 nm^(-3),which is~80 times that of the photonic crystal(PhC)nanobeam and~100 times that of the hybrid point-defect PhC bowtie plasmonic nanocavity,where Q_(c) is optical quality factor and V is mode volume.The optome-chanical single-photon coupling strength can reach 12 MHz,which is an order of magnitude larger than that of the PhC nanobeam.In addition,the mechanical zero-point fluctuation amplitude is 85 fm and the efficient mass is 0.27 zg,which is much smaller than the PhC nanobeam.The phononic superlattice-Ag nanocavity optomechanical devices hold great potential for applications in the field of integrated quantum optomechanics,quantum information,and terahertz-light transducer. | Zhenyao Li Haonan Chang Jia-Min Lai Feilong Song Qifeng Yao Hanqing Liu Haiqiao Ni Zhichuan Niu Jun Zhang | 2023 | Journal of Semiconductors2023，44，8： | 0 |
| 12 | Single-electron pumping in a ZnO single-nanobelt quantum dot transistor显示文摘Diluted magnetic semiconductors(DMSs)have traditionally been employed to implement spin-based quantum computing and quantum information processing.However,their low Curie temperature is a major hurdle in their use in this field,which creates the necessity for wide bandgap DMSs operating at room temperature.In view of this,a single-electron transistor(SET)with a global back-gate was built using a wide bandgap ZnO nanobelt(NB).Clear Coulomb oscillations were observed at 4.2 K.The periodicity of the Coulomb diamonds indicates that the Coulomb oscillations arise from single quantum dots of uniform size,whereas quasi-periodic Coulomb diamonds correspond to the contribution of multi-dots present in the ZnO NB.By applying an AC signal to the global back-gate across a Coulomb peak with varying frequencies,single-electron pumping was observed;the increase in current was equal to the production of electron charge and frequency.The current accuracy of about 1%for both single-and double-electron pumping was achieved at a high frequency of 25 MHz.This accurate single-electron pumping makes the ZnO NB SET suitable for single-spin injection and detection,which has great potential for applications in quantum information technology. | Hassan Ali Jing Tang Kai Peng SiBai Sun Attia Falak FeiLong Song ShiYao Wu ChenJiang Qian Meng Wang XiTian Zhang Muhammad Aftab Rafiq XiuLai Xu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，6： | 0 |
| 13 | Phase formation,texture evolutions,and mechanical behaviors of Al_(0.5)CoCr_(0.8)FeNi_(2.5)V_(0.2) high-entropy alloys upon cold rolling显示文摘The cold rolling(CR)reduction dependence of microstructure evolutions and mechanical properties for Al_(0.5)CoCr_(0.8)FeNi_(2.5)V_(0.2) high-entropy alloy(HEA)were investigated.The HEA remains FCC structures consisting of nanoscale ordered L12 phase,confirming the phase formation prediction.With increasing CR reduction,the textures transform from random ones to FCC rolling ones accompanied by dense slip bands and deformation twins.Under a 50%CR reduction,the deformation textures started to become evident and were governed by typical{111}<112>F,{110}<100>Goss and{112}<111>Cu texture components.When the CR reduction approached 90%,the deformation textures mainly contained the{110}<111>A,{114}<110>X,and{112}<111>Cu texture components.As a result,both Vickers hardness and ultimate strength increased,but the ductility decreased roughly.The enhanced strength should be attributed to the anisotropy and work hardening behavior from textures.The plastic deformation for the samples under low CR reductions was dominated by deformation twins and slip bands.However,under high CR reductions,the textures severely impeded the further propagation of pre-existing slip bands,leading to the rapid decrease of ductility.Therefore,the CR reduction should be carefully designed before optimal heat treatments to enhance the strength and ductility synergy. | Tongtong Sun Weidong Song Feilong Shan Kaikai Song Kun Zhang Chuanxiao Peng Honggang Sun Lina Hu | 2022 | Progress in Natural Science:Materials International2022，32，2： | 0 |
| 14 | Paleoenvironmental Characteristics of Paleogene Lacustrine Source Rocks in the Western Bozhong Sag,Bohai Bay Basin,China:Evidence from Biomarkers,Major and Trace Elements显示文摘The organic matter(OM)enrichment mechanisms and depositional environment characteristics of lacustrine source rocks in the western Bozhong Sag,Bohai Bay Basin in Northeast China remain controversial.To address these issues,based on Rock-Eval pyrolysis,kerogen macerals,H/C and O/C ratios,GC-MS,major and trace elements,the Dongying Formation Member(Mbr)3(E_(3)d_(3)),the Shahejie Formation mbrs 1 and 2(E_(2)s_(1+2)),and the Shahejie Mbr 3(E_(2)s_(3))source rocks in the western Bozhong Sag were studied.The above methods were used to reveal their geochemical properties,OM origins and depositional environments,all of which indicate that E_(2)s_(1+2)and E_(2)s_(3)are excellent source rocks,and that E_(3)d_(3)is of the second good quality.E_(3)d_(3)source rocks were formed under a warm and humid climate,mainly belong to fluvial/delta facies,the E_(3)d_(3)sediments formed under weakly oxidizing and freshwater conditions.Comparatively,the depositional environments of E_(2)s_(1+2)source rocks were arid and cold climate,representing saline or freshwater lacustrine facies,and the sediments of E_(2)s_(1+2)belong to anoxic or suboxic settings with large evaporation and salinity.During the period of E_(2)s_(3),the climate became warm and humid,indicating the freshwater lacustrine facies,and E_(2)s_(3)was characterized by freshwater and abundant algae.Moreover,compared with other intervals,the OM origin of E_(3)d_(3)source rocks has noticeable terrestrial input.The OM origin of the E_(2)s_(1+2)and E_(2)s_(3)are mainly plankton and bacteria.Tectonic subsidence and climate change have affected the changes of the depositional environment in the western Bozhong Sag,thus controlling the distribution of the source rocks,the geochemical characteristics in the three intervals of lacustrine source rocks have distinct differences.Overall,these factors are effective to evaluate the paleoenvironmental characteristics of source rocks by biomarkers,major and trace elements.The established models may have positive implications for research of lacustrine source rocks in offshore areas with few drillings. | WANG Xiang LIU Guangdi SONG Zezhang SUN Mingliang WANG Xiaolin WANG Feilong CHEN Rongtao GENG Mingyang LI Yishu | 2024 | Acta Geologica Sinica(English Edition)2024，98，1： | 0 |
