| 1 | Zircon SHRIMP Dating for the Weiya Pluton, Eastern Tianshan: Its Geological Implications显示文摘The timing of the emplacement of the Weiya pluton remains controversial due to the absence of systematic and precise dating. This paper reports zircon SHRIMP U-Pb dating of different lithologic phases in the Weiya pluton, and discusses the genesis and tectonic environment. The ages of gabbro, quartz syenite, diorite porphyrite and fine-grained granite are 236?6 Ma, 246?6 Ma, 233?8 Ma and 237?8 Ma, respectively. All these phases were formed in early-middle Indosinian (Triassic) in a post-orogenic environment. In addition to underplating, intraplating of mantle-derived magmas is also a substantial mechanism for magma generation and vertical accretion of the continental crust. Granitoid rocks are important products of vertical continental accretion as underplating evolves gradually to intraplating. The existence of post-orogenic Indosinian granites shows that the middle Tianshan orogenic belt underwent an important tectonic conversion from the Paleo-Asian ocean subduction-collision system to the Paleo-Tethys ocean regime. | ZHANG Zunzhong GU Lianxing WU Changzhi LI Weiqiang XI Aihua WANG Shuo | 2005 | Acta Geologica Sinica(English Edition)2005，79，4： | 53 |

| 3 | Controllable optical activity with non-chiral plasmonic metasurfaces显示文摘Optical activity is the rotation of the plane of linearly polarized light along the propagation direction as the light travels through optically active materials.In existing methods,the strength of the optical activity is determined by the chirality of the materials,which is difficult to control quantitatively.Here we numerically and experimentally investigated an alternative approach to realize and control the optical activity with non-chiral plasmonic metasurfaces.Through judicious design of the structural units of the metasurfaces,the right and left circular polarization components of the linearly polarized light have different phase retardations after transmitting through the metasurfaces,leading to large optical activity.Moreover,the strength of the optical activity can be easily and accurately tuned by directly adjusting the phase difference.The proposed approach based on non-chiral plasmonic metasurfaces exhibits large optical activity with a high controllable degree of freedom,which may provide more possibilities for applications in photonics. | Ping Yu Jianxiong Li Chengchun Tang Hua Cheng Zhaocheng Liu Zhancheng Li Zhe Liu Changzhi Gu Junjie Li Shuqi Chen Jianguo Tian | 2016 | Light(Science & Applications)2016，5，1： | 8 |
| 4 | Directly patterned substrate-free plasmonic “nanograter” structures with unusual Fano resonances显示文摘The application of three-dimensional(3D)plasmonic nanostructures as metamaterials(MMs),nano-antennas,and other devices faces challenges in producing metallic nanostructures with easily definable orientations,sophisticated shapes,and smooth surfaces that are operational in the optical regime and beyond.Here,we demonstrate that complex 3D nanostructures can be readily achieved with focused-ion-beam irradiation-induced folding and examine the optical characteristics of plasmonic“nanograter”structures that are composed of free-standing Au films.These 3D nanostructures exhibit interesting 3D hybridization in current flows and exhibit unusual and well-scalable Fano resonances at wavelengths ranging from 1.6 to 6.4 mm.Upon the introduction of liquids of various refractive indices to the structures,a strong dependence of the Fano resonance is observed,with spectral sensitivities of 1400 nm and 2040 nm per refractive index unit under figures of merit of 35.0 and 12.5,respectively,for low-order and high-order resonance in the near-infrared region.This work indicates the exciting,increasing relevance of similarly constructed 3D free-standing nanostructures in the research and development of photonics and MMs. | Ajuan Cui Zhe Liu Jiafang Li Tiehan H Shen Xiaoxiang Xia Zhiyuan Li Zhijie Gong Hongqiang Li Benli Wang Junjie Li Haifang Yang Wuxia Li Changzhi Gu | 2015 | Light(Science & Applications)2015，4，1： | 8 |
| 5 | Fabrication technique of micro/nano-scale speckle patterns with focused ion beam显示文摘The fabrication technique of micro/nano-scale speckle patterns with focused ion beam (FIB) system is studied for digital image correlation (DIC) measurement under a scanning electron microscope (SEM).The speckle patterns are fabricated by directly etching the counterpart of the specimen to the black part of a template.Mean intensity gradient is used to evaluate the quality of these SEM images of speckle patterns fabricated based on different templates to select an optimum template.The pattern size depending on the displacement measurement sensitivity is adjusted by altering the magnification of FIB according to the relation curve of the etching size versus magnification.The influencing factors including etching time and ion beam current are discussed.Rigid body translation tests and rotation tests are carried out under SEM to verify the reliability of the fabricated speckle patterns.The calculated values are in good agreement with the imposed ones. | LI YanJie XIE HuiMin LUO Qiang GU ChangZhi HU ZhenXing CHEN PengWan ZHANG QingMing | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，6： | 7 |

| 7 | A 23 GHz high-temperature superconducting microstrip filter for radio astronomy显示文摘This paper reports a 6-pole high-temperature superconducting (HTS) microstrip bandpass filter for radio astronomy applications. The filter has a center frequency of 23 GHz and a bandwidth the 2 GHz. We have made many efforts, such as adopting 0.25-mm-thick substrate, carefully designing the housing box and filter layout, to solve the problems in realizing a K-band planar filter. A special straight-line half-wavelength resonator (center-widen resonator) was also designed to reduce the insertion loss of the filter. The measured results showed a midband insertion loss of 0.11 dB with a ripple of 0.4 dB, and a return loss better than 11.5 dB. Good agreement was obtained between simulated and measured results. | GAO Lu GUO Jin WANG YueHui YU Tao ZHANG Qiang LI ChunGuang ZHANG XueQiang LI Hong LI JunJie LI WuXia GU ChangZhi MENG JiBao FENG Ji HE YuSheng | 2009 | Chinese Science Bulletin2009，54，19： | 6 |
| 8 | Polarization multiplexing for double images display显示文摘Metasurface provides subwavelength structures for manipulating wavefronts of light. The benefits of subwavelength components offer a continuous modulation of amplitude, phase, and polarization, thus eliminating the production of higher-order images and improving the utilization of light intensity. Despite the rapid progress in this field, multiparameter control of light using single layer metasurface is rarely reported. In fact, multiparameter control of light helps to improve information storage capacity and image fidelity. With simultaneous manipulation of polarization and amplitude at each pixel, it is possible to encode two separate images into one metasurface and reconstruct them under proper conditions. In a proof of concept experiment, we demonstrate an independent display of two binary images at the same position with polarization de-multiplexing from a single metasurface. This unique technology of encoding two images through amplitude and polarization manipulation provides a new opportunity for various applications in, such as encryption, information storage, polarization holograms, optical communications and fundamental physics. | Jinying Guo Teng Wang Baogang Quan Huan Zhao Changzhi Gu Junjie Li Xinke Wang Guohai Situ Yan Zhang | 2019 | Opto-Electronic Advances2019，2，7： | 4 |
| 9 | Space qualification mechanical tests of HTS filters for satellite application显示文摘High performance high-temperature superconducting (HTS) filters have been designed and constructed for satellite application. The filters are actually a superconducting integration of an 8-pole band-pass filter with an adjustable band-stop filter onto a single piece of LaAlO3 substrate (with dimension of 0.5×45×20 mm3). Typical results of the filters, i.e., Filters A (made by YBCO) & B (made by TBCCO) will be reported. The measured responses of Filter A showed excellent specifications, e.g., an insertion loss less than 0.1 dB, a return loss better than -22.5 dB in pass-band, band-edge steepness greater than 12 dB/MHz and out-of-band rejection at a certain band deeper than -110 dB. To satisfy the requirement of rocket launch and space operation, three filters of the above design have undergone mechanical environmental simulation tests for space qualification. Detailed analysis of the response curves of Filter B measured before and after the tests showed that no noticeable change in the per-formance can be found. All the filters passed the rigorous ground simulation tests, which is the first time in China for HTS devices and provided a solid foundation for satellite applications of high-temperature superconductors in the near future. | HUANG JianDong SUN Liang LI ShunZhou MENG QingDuan ZHANG Qiang LI Fei ZHANG XueQiang LI ChunGuang HE AiSheng LI Hong GU ChangZhi LUO Qiang SUN QinFen WANG XiaoLin SUN YiFan WANG ZhiBing WANG YunFei LUO Sheng HE YuSheng | 2007 | Chinese Science Bulletin2007，52，13： | 3 |
| 10 | A kind of double-sided porous anodic alumina membrane fabricated with the three-step anodic oxidation method显示文摘The porous anodic alumina membranes(PAAMs)have been successfully used as templates for the fabrication of functional nano-materials due to their outstanding regularity and physicochemical properties.In this paper,a transparent double-sided anodic alumina membrane with ultra-thin aluminum substrate was fabricated with the three-step anodic oxidation method in the oxalic acid electrolyte.The characters such as the top-surface morphology,membrane thickness,and depth of nanopores of this three-layer(Al2O3-Al-Al2O3)sandwiched nano-structure were controllable through regulating the main anodic oxidation conditions,e.g.,anodic oxidation time of various steps,coating remove process.The experiments data revealed that the aluminum substrate is exponential declined with the oxidation time when it was approximately reduced by a few micrometers.This new double-sided anodic alumina membrane can be used as the high-quality functional field emission materials and templates. | ZHANG Chen WANG KaiGe GAO ZeYang WU JunJun REN JunYing ZHANG LiangLiang GU ChangZhi BAI JinTao | 2014 | Science China(Technological Sciences)2014，57，2： | 2 |

| 13 | Triangulation of red sprites observed above a mesoscale convective system in North China显示文摘The triangulation of red sprites was obtained, based on concurrent observations over a mesoscale convective system(MCS) in North China from two stations separated by about 450 km. In addition, broadband sferics from the sprite-producing lightning were measured at five ground stations, making it possible to locate and identify the individual causative lightning discharges for different elements in this dancing sprite event. The results of our analyses indicate that the sprites were produced above the trailing stratiform region of the MCS, and their parent strokes were located mainly in the peripheral area of the stratiform. The lateral offset between sprites and causative strokes ranges from a few km to more than 50 km. In a particularly bright sprite, with a distinct halo feature and streamers descending down to an altitude of approximately 48 km, the sprite current signal identified in the electric sferic, measured at a range of about 1,110 km, peaked at approximately 1 ms after the return stroke. | YongPing Wang GaoPeng Lu Ming Ma HongBo Zhang YanFeng Fan GuoJin Liu ZheRun Wan Yu Wang Kang-Ming Peng ChangZhi Peng FeiFan Liu BaoYou Zhu BinBin Ni XuDong Gu Long Chen Juan Yi RuoXian Zhou | 2019 | Earth and Planetary Physics2019，3，2： | 2 |
| 14 | 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 |

| 18 | Direct bandgap engineering with local biaxial strain in few-layer MoS2 bubbles显示文摘Nano Research volume 13,pages2072–2078(2020)Cite this article 211 Accesses Metrics details Abstract Strain engineering provides an important strategy to modulate the optical and electrical properties of semiconductors for improving devices performance with mechanical force or thermal expansion difference.Here,we present the investigation of the local strain distribution over few-layer MoS2 bubbles,by using scanning photoluminescence and Raman spectroscopies.We observe the obvious direct bandgap emissions with strain in the few-layer MoS2 bubble and the strain-induced continuous energy shifts of both resonant excitons and vibrational modes from the edge of the MoS2 bubble to the center(10μm scale),associated with the oscillations resulted from the optical interference-induced temperature distribution.To understand these results,we perform ab initio simulations to calculate the electronic and vibrational properties of few-layer MoS2 with biaxial tensile strain,based on density functional theory,finding good agreement with the experimental results.Our study suggests that local strain offers a convenient way to continuously tune the physical properties of a few-layer transition metal dichalcogenides(TMDs)semiconductor,and opens up new possibilities for band engineering within the 2D plane. | Yang Guo Bin Li Yuan Huang Shuo Du Chi Sun Hailan Luo Baoli Liu Xingjiang Zhou Jinlong Yang Junjie Li Changzhi Gu | 2020 | Nano Research2020，13，8： | 1 |
