| 1 | Optical tuning of exciton and trion emissions in monolayer phosphorene显示文摘Monolayer phosphorene provides a unique two-dimensional(2D)platform to investigate the fundamental dynamics of excitons and trions(charged excitons)in reduced dimensions.However,owing to its high instability,unambiguous identification of monolayer phosphorene has been elusive.Consequently,many important fundamental properties,such as exciton dynamics,remain underexplored.We report a rapid,noninvasive,and highly accurate approach based on optical interferometry to determine the layer number of phosphorene,and confirm the results with reliable photoluminescence measurements.Furthermore,we successfully probed the dynamics of excitons and trions in monolayer phosphorene by controlling the photo-carrier injection in a relatively low excitation power range.Based on our measured optical gap and the previously measured electronic energy gap,we determined the exciton binding energy to be~0.3 eV for the monolayer phosphorene on SiO_(2)/Si substrate,which agrees well with theoretical predictions.A huge trion binding energy of~100 meV was first observed in monolayer phosphorene,which is around five times higher than that in transition metal dichalcogenide(TMD)monolayer semiconductor,such as MoS_(2).The carrier lifetime of exciton emission in monolayer phosphorene was measured to be,220 ps,which is comparable to those in other 2D TMD semiconductors.Our results open new avenues for exploring fundamental phenomena and novel optoelectronic applications using monolayer phosphorene. | Jiong Yang Renjing Xu Jiajie Pei Ye Win Myint Fan Wang Zhu Wang Shuang Zhang Zongfu Yu Yuerui Lu | 2015 | Light(Science & Applications)2015，4，1： | 8 |
| 2 | Evidence for metasomatic mantle carbonatitic magma extrusion in Mesoproterozoic ore-hosting dolomite rocks in the middle Kunyang rift, central Yunnan, China显示文摘The Kunyang rift lying on the western margin of the Yangtze platform is a rare Precambrian Fe-Cu mineralization zone. WudingLufeng basin that is an important part of the zone is located on the west edge in the middle of the rift. The most important ore-hosting rocks are Mesoproterozoic dolomite rocks in the basin controlled by a ring fracture system, which is a fundamental structure of the basin. Plenty of silicate minerals and acicular apatite, feldspar phenocrysts and small vesicular, flown line and flown plane structures, melt inclusion and high temperature fluid inclusion found in most ore-hosting dolomites suggest that this kind of rocks could not be sedimentary dolomite, marble or hydrothermal carbonate rocks. The Zr/Hf and Nb/Ta values of the rocks are identical with those of associated mantle-derived rocks, and vary widely. For the monomineral dolomite, d18OSMOW‰ = +5.99 to +18.4 and d13CPDB‰ = à3.01 to +0.94, which fall within the range for all carbonatitic volcanic rocks of the world. As for the accessory minerals, the values of d18OSMOW‰ of magnetite (=+3.47 to +5.99‰) are close to that of the mantle (<5.7%), and the d34S‰ values of sul?des (à5.09 to +5.78, averaging +1.50) are close to that of meteorite. For all the ore-bearing dolomite rocks, eNd = +0.19 to +2.27, and the calculated ISr = 0.699143, while for the associated mantle-derived rocks, eNd = +3.18 to +3.72. All the data suggest that the mineral assemblage is not only igneous but also of metasomatic mantle origin. And the presence of acicular apatite indicates that the rocks were formed by magma rapidly cooling. And the phenocryst texture and vesicular, flown and ropy and pyroclastic structures suggest that the igneous rocks were extrusive. Therefore, the ore-bearing dolomite rocks are carbonatitic volcanic rocks. This conclusion implies that most iron and copper ore deposits hosted in the dolomite rocks should be of the carbonatite type. | Yongbei Zhang Hua Bi Longshi Yu Shihua Sun Jiaxiang Qiu Chengyan Xu Hao Wang Renjing Wang | 2008 | Progress in Natural Science:Materials International2008，18，8： | 2 |

| 6 | Atomically thin optical lenses and gratings显示文摘Two-dimensional(2D)materials have emerged as promising candidates for miniaturized optoelectronic devices due to their strong inelastic interactions with light.On the other hand,a miniaturized optical system also requires strong elastic light–matter interactions to control the flow of light.Here we report that a single-layer molybdenum disulfide(MoS2)has a giant optical path length(OPL),around one order of magnitude larger than that from a single-layer of graphene.Using such giant OPL to engineer the phase front of optical beams we have demonstrated,to the best of our knowledge,the world’s thinnest optical lens consisting of a few layers of MoS2 less than 6.3 nm thick.By taking advantage of the giant elastic scattering efficiency in ultra-thin high-index 2D materials,we also demonstrated high-efficiency gratings based on a single-or few-layers of MoS2.The capability of manipulating the flow of light in 2D materials opens an exciting avenue towards unprecedented miniaturization of optical components and the integration of advanced optical functionalities.More importantly,the unique and large tunability of the refractive index by electric field in layered MoS2 will enable various applications in electrically tunable atomically thin optical components,such as micro-lenses with electrically tunable focal lengths,electrical tunable phase shifters with ultra-high accuracy,which cannot be realized by conventional bulk solids. | Jiong Yang Zhu Wang Fan Wang Renjing Xu Jin Tao Shuang Zhang Qinghua Qin Barry Luther-Davies Chennupati Jagadish Zongfu Yu Yuerui Lu | 2016 | Light(Science & Applications)2016，5，1： | 1 |

| 8 | Isolation, Identification and Pathogenicity Evaluation of Pathogens of Soybean Bacterial Diseases显示文摘In order to research soybean bacterial diseases in Heilongjiang Province,a bacterial strain was isolated from diseased leaves of Suinong 14 collected from Harbin Yanjiagang farm. The pathogen had been carried out antibiotic resistance identification,molecular identification,re-inoculation identification and pathogenicity identification respectively. By Gram staining,pathogen inoculation test,16 S r DNA molecular identification,the pathogen was determined as Pseudomonas syringae and named Psgneau 2. The isolated strain presented resistance to 25,50 and 100 μg/m L ampicillin and carbenicillin,but susceptible to spectinomycin,rifampicin,kanamycin,gentamicin,tetracycline and chloramphenicol. Ten soybean varieties were inoculated with Psgneau 2,in which Suinong 14 was more susceptible than other varieties and Hefeng 35 presented higher resistance to Psgneau 2. | Zhang Hui Yu Renjing Zou Jianan Xin Dawei Hu Zhenbang Zhang Yong Liu Chunyan Chen Qingshan | 2016 | Plant Diseases and Pests2016，7，5： | 0 |
| 9 | Structural plasticity-based hydrogel optical Willshaw model for one-shot on-the-fly edge learning显示文摘Autonomous one-shot on-the-fly learning copes with the high privacy,small dataset,and in-stream data at the edge.Implementing such learning on digital hardware suffers from the well-known von-Neumann and scaling bottlenecks.The optical neural networks featuring large parallelism,low latency,and high efficiency offer a promising solution.However,ex-situ training of conventional optical networks,where optical path configuration and deep learning model optimization are separated,incurs hardware,energy and time overheads,and defeats the advantages in edge learning.Here,we introduced a bio-inspired material-algorithm co-design to construct a hydrogel-based optical Willshaw model(HOWM),manifesting Hebbian-rule-based structural plasticity for simultaneous optical path configuration and deep learning model optimization thanks to the underlying opto-chemical reactions.We first employed the HOWM as an all optical in-sensor AI processor for one-shot pattern classification,association and denoising.We then leveraged HOWM to function as a ternary content addressable memory(TCAM)of an optical memory augmented neural network(MANN)for one-shot learning the Omniglot dataset.The HOWM empowered one-shot on-the-fly edge learning leads to 1000boost of energy efficiency and 10boost of speed,which paves the way for the next-generation autonomous,efficient,and affordable smart edge systems. | Dingchen Wang Dingyao Liu Yinan Lin Anran Yuan Woyu Zhang Yaping Zhao Shaocong Wang Xi Chen Hegan Chen Yi Zhang Yang Jiang Shuhui Shi Kam Chi Loong Jia Chen Songrui Wei Qing Wang Hongyu Yu Renjing Xu Dashan Shang Han Zhang Shiming Zhang Zhongrui Wang | 2023 | InfoMat2023，5，4： | 0 |
