| 2 | New progress of plasmonics in complex metal nanostructures显示文摘Noble metal nanostructures possess novel optical properties because of their collective electronic oscillations,known as surface plasmons(SPs).The resonance of SPs strongly depends on the material,surrounding environment,as well as the geometry of the nanostructures.Complex metal nanostructures have attracted research interest because of the degree of freedom in tailoring the plasmonic properties for more advanced applications that are unattainable by simple ones.In this review,we discuss the plasmonic properties of several typical types of complex metal nanostructures,that is,electromagnetically coupled nanoparticles(NPs),NPs/metal films,NPs/nanowires(NWs),NWs/NWs,and metal nanostructures supported or coated by dielectrics.The electromagnetic field enhancement and surface-enhanced Raman scattering applications are mainly discussed in the NPs systems where localized SPs have a key role.Propagating surface plasmon polaritons and relevant applications in plasmonic routers and logic gates using NWs network are also reviewed.The effect of dielectric substrates and surroundings of metal nanostructures to the plasmonic properties is also discussed. | TIAN XiaoRui TONG LianMing XU HongXing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，12： | 4 |
| 3 | Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process. | Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

| 5 | Laser irradiation induced spectral evolution of the surface-enhanced Raman scattering(SERS) of 4-tert-butylbenzylmercaptan on gold nanoparticles assembly显示文摘The spectral evolution of the surface-enhanced Raman scattering (SERS) of 4-tert-butylbenzylmer-captan (4-tBBM) on gold nanoparticles assembly under laser irradiation is reported. The relative intensities of typical peaks in the spectrum of 4-tBBM gradually change with irradiation time. Comparison of the rate of spectral changes under several experimental conditions indicates that the surface plasmon resonance (SPR) induced heat in the gold nanoparticles assembly is the origin of the spectral evolution. During the process of self-assembly, 4-tBBM molecules do not form a compact ordered monolayer because of the spatial hindrance of the 4-tert-butyl end group. The heat induced by laser irradiation drives the 4-tBBM molecules to rearrange to a more stable orientation. | TONG LianMing ZHU Tao LIU ZhongFan | 2007 | Science China Chemistry2007，50，4： | 1 |
| 6 | Ultrafast growth of wafer-scale fold-free bilayer graphene显示文摘Bilayer graphene provides a versatile platform for exploring a variety of intriguing phenomena and shows much promise for applications in electronics,optoelectronics,etc.Controlled growth of large-area bilayer graphene is therefore highly desired yet still suffers from a slow growth rate and poor layer uniformity.Meanwhile,graphene wrinkles,including folds and ripples,form during cooling due to the thermal contraction mismatch between graphene and the metal substrates,and have been far from suppressed or eliminated,especially in bilayer graphene,which would greatly degrade the extraordinary properties of graphene.Here we report the ultrafast growth of wafer-scale fold-free bilayer graphene by chemical vapor deposition.Through well-tuning the alloy thickness and strain regulation of the single-crystal CuNi(111)/sapphire,the full coverage of a 2-inch fold-free bilayer graphene wafer via mainly isothermal segregation has been achieved as fast as 30 s.The tensile-strained CuNi(111)film reduces the thermal contraction mismatch and suppresses the formation of graphene folds during cooling,which is directly observed through in situ optical microscopy.The ultraflat bilayer graphene exhibits wafer-scale uniformity in electrical performance and enhanced mechanical property comparable to the exfoliated ones.Our results offer a promising route for largescale production of bilayer graphene and enable its various applications. | Jilin Tang Yuechen Wang Yuwei Ma Xiaoyin Gao Xin Gao Ning Li Yani Wang Shishu Zhang Liming Zheng Bing Deng Rui Yan Yisen Cao Ronghua Zhang Lianming Tong Jin Zhang Peng Gao Zhongfan Liu Xiaoding Wei Hongtao Liu Hailin Peng | 2023 | Nano Research2023，16，7： | 0 |
| 7 | Abnormal intensity and polarization of Raman scattered light at edges of layered MoS_(2)显示文摘The edges of two-dimensional(2D)materials can exhibit special structure and thus distinctive properties differing from the interior,such as the modified photoluminescence emission,the improved electrocatalytic activity,and the enhanced nonlinear optical response.In this work,we report the observation of abrupt enhancement of Raman scattered light at edges of layered MoS_(2),which is closely related to the polarization of the incident light.More importantly,the intensity of out-of-plane A1g mode is enhanced much more obviously than the in-plane E_(2g)^(1)mode.The unique optical effect at edges is also reflected on the alteration of Raman selection rule.The forbidden Raman modes are observed at edge region,and the polarization of Raman scattered light can be modulated by the edge structure,which differs obviously from that of the interior.We attribute these particular performances to the modulation of the intensity and distribution of the electric field for the incident and Raman scattered light at the edge.This work provides a systematic research on the intensity and polarization modulation of the Raman scattering at edges,which would be helpful for understanding the distinctive optical properties of the edge structure. | Yan Zhao Liheng Zheng Shiyi Han Bo Xu Zheyu Fang Jin Zhang Lianming Tong | 2022 | Nano Research2022，15，7： | 0 |
| 8 | Tuning bandstructure of folded MoS_(2) through fluid dynamics显示文摘The variation of interlayer coupling can greatly affect the bandstructure of few layered transition metal dichalcogenides(TMDs),for instance,transition of indirect-to-direct bandgap and vice versa,which is correlated with the charge carrier and optical density.However,methods that can modulate the coupling strength in a controllable way are still lacking.Here,we report a fluidic dynamic strategy to tune the interlayer coupling of folded bi-layer MoS_(2).By controlling the flow direction and particle size of the fluid,mono-layer MoS_(2)can be folded into bi-layer with a controlled folding direction for designated twist angles as well as tunable interlayer coupling.Compared with normally folded bi-layer MoS_(2),the photoluminescence(PL)peak of the direct-bandgap transition for folded bi-layer MoS_(2)by fluid flow is weakened accompanied with the re-appearance of indirect-bandgap transition peak.Besides,the fluid flow creates a clear trajectory on the folded MoS_(2),exhibiting various degrees of interlayer coupling along it.Field-effect transistors(FETs)were further fabricated on tunably coupled folded-bi-layers,proving that the bandstructure and electrical property is strongly correlated with the degree of interlayer coupling.This fluidic dynamic strategy can be extended to other TMDs on any substrate,and together with its excellent capability in controlled interlayer coupling,it will provide a new way for the development of TMDs optoelectronics. | Zihan Zhao Weifeng Zhang Yan Zhang He Hao Shishu Zhang Lianming Tong Banghua Peng Nan Liu | 2022 | Nano Research2022，15，3： | 0 |
| 9 | Local modulation of exc辻ons and trions in monolayer WS2 by carbon nanotubes显示文摘Mixed dimensional van der Waals(VdW)heterostructures constructed by one-dimensional(1D)and two-dimensional(2D)materials exhibit extra degree of freedom to modulate the electronic and optical properties due to the combination of difterent dimensionalities.The charge transfer at the intertace between 1D and 2D materials plays a crucial role in the optoelectronic properties and performance of the heterostructure-based devices.Here,we stacked single-walled carbon nanotubes(SWNTs)on monolayer WS2 for a mixed dimensional vdW heterostructure,and investigated the local modulation of excitions and trions in WS2 by SWNTs.Different directions of charge transfer between SWNTs and WSz are evidenced by the photoluminescence(PL)spectra of WS2.The PL intensity can be either enhanced or weakened by individual SWNTs.In our work,the PL intensity of WS2 is enhanced and the exciton peak position heterostructure is red-shifted about 3 meV due to the charge transfer from WS2 to an individual SWNT(SWNT#1).The change of PL by another SWNT(SWNT#2)can not be well-resolved in far fild,but scanning near field optical microscope(SNOM)measurements show that the PL intensity of WS2 is weakened by the SWNT.The peak position of exciton is blue-shifted by^1 meV while that of trion is redshifted by^1 meV due to the charge transfer from the SWNT to WS2,These results give insight into the charge transfer at the interface of SWNTWS2 heterostructure,and can be useful for design of optoelectronic devices based on mixed dimensional vdW heterostructures. | Rui Feng Shicheng Xu Weiming Liu Peng Gao Jin Zhang Lianming Tong | 2020 | Nano Research2020，13，7： | 0 |
| 10 | Multishelled CuO/Cu_(2)O induced fast photo-vapour generation for drinking water显示文摘Solar thermal interfacial water evaporation is proposed as a promising route to address freshwater scarcity,which can reduce energy consumption and have unlimited application scenarios.The large semiconductor family with controllable bandgap and good chemo-physical stability are considered as good candidates for photo-evaporation.However,the evaporation rate is not satisfactory because the rational control of nano/micro structure and composition is still in its infancy stage.Herein,by systemically analyzing the photo-thermal evaporation processes,we applied the hollow multishelled structure(HoMS)into this application.Benefiting from the multishelled and hierarchical porous structure,the light absorption,thermal regulation,and water transport are simultaneously optimized,resulting in a water evaporation rate of 3.2 kg·m^(-2)·h^(-1),which is among the best performance in solar-vapour generation.The collected water from different water resources meets the World Health Organization standard for drinkable water.Interestingly,by using the CuO/Cu_(2)O system,reactive oxygen species were generated for water disinfection,showing a new route for efficient solar-vapour generation and a green way to obtain safe drinking water. | Xuanbo Chen Ping Li Jiao Wang Jiawei Wan Nailiang Yang Bo Xu Lianming Tong Lin Gu Jiang Du Jianjian Lin(✉) Ranbo Yu Dan Wang | 2022 | Nano Research2022，15，5： | 0 |
| 11 | The road to chirality-specific growth of single-walled carbon nanotubes显示文摘Moore’s law has been declared to be eventually nearing its end after nearly five decades,with silicon being the main building block for all computing chips[1].The main roadblock in the development of transistors is the occurrence of the tunneling effect when the devices become small enough.A possible solution is finding alternative materials to fabricate a‘millivolt switch’,which is at least as fast as silicon counterparts and generates much less heat. | shuchen zhang lianming tong jin zhang | 2018 | National Science Review2018，5，3： | 0 |
| 12 | The helicity of Raman scattered light:principles and applications in two-dimensional materials显示文摘Raman spectroscopy has been not only a technique for characterizing the composition and lattice structure of materials,but also a platform to explore the electron-photon and electron-phonon couplings.When excited by circularly polarized light,the Raman scattered light can carry a spin angular momentum±h,which adds a new degree of freedom to study the Raman scattering process.This review explains the principles of the helicity of Raman scattered light excited by circular polarization,and introduces the recent advances in the fundamentals and applications of helicity-resolved Raman scattering in two dimensional(2 D)materials,including the assignment of overlapped Raman modes,the characterization of exciton-phonon coupling and the application in chiral optics.We hope that this review will give a comprehensive understanding of the helicity selection rule in the Raman scattering process and inspire more exploration on the applications of the helicity of Raman scattered light. | Yan Zhao Bo Xu Lianming Tong Jin Zhang | 2022 | Science China Chemistry2022，65，2： | 0 |
