| 1 | Theoretical study of ZnO adsorption and bonding on Al_2O_3(0001) surface显示文摘ZnO adsorption on sapphire (0001) surface is theoretically calculated by using a plane wave ultrasoft pseudo-potential method based on ab initio molecular dynamics. The results reveal that the surface relaxation in the first layer Al-O is reduced, even eliminated after the surface adsorption of ZnO, and the chemical bonding energy is 434.3(±38.6) kJ·mol?1. The chemical bond of ZnO (0.185 ± 0.01 nm) has a 30° angle away from the adjacent Al-O bond, and the stable chemical adsorption position of the Zn is deflected from the surface O-hexagonal symmetry with an angle of about 30°. The analysis of the atomic populations, density of state and bonding electronic density before and after the adsorption indicates that the chemical bond formed by the O2 of the ZnO ? and the surface Al3+ has a strong ionic bonding characteristic, while the chemical bond formed by the Zn2+ and the surface O2 has an obvious covalent characteristic, which ? comes mainly from the hybridization of the Zn 4s and the O 2p and partially from that of the Zn 3d and the O 2p. | LI Yanrong1,YANG Chun1,2,XUE Weidong1,LI Jinshan3 & LIU Yonghua3 1.Institute of Microelectronics and Solid State Electronics,University of Electronic Science and Technol- ogy of China,Chengdu 610054,China 2.Institute of Mathematics and Software Science,Sichuan Normal University,Chengdu 610068,China 3.Institute of Chemical Materials,China Academy of Engineering Physics,Mianyang 621000,China | 2004 | Science China(Physics,Mechanics & Astronomy)2004，47，6： | 1 |
| 2 | Solar X-ray and EUV imager on board the FY-3E satellite显示文摘The solar X-ray and Extreme Ultraviolet Imager(X-EUVI),developed by the Changchun Institute of Optics,Fine Mechanics and Physics,Chinese Academy of Sciences(CIOMP),is the first space-based solar X-ray and Extreme ultraviolet(EUV)imager of China loaded on the Fengyun-3E(FY-3E)satellite supported by the China Meteorological Administration(CMA)for solar observation.Since started work on July 11,2021,X-EUVI has obtained many solar images.The instrument employs an innovative dual-band design to monitor a much larger temperature range on the Sun,which covers 0.6-8.0 nm in the X-ray region with six channels and 19.5 nm in the EUV region.X-EUVI has a field of view of 42′,an angular resolution of 2.5″per pixel in the EUV band and an angular resolution of 4.1″per pixel in the X-ray band.The instrument also includes an X-ray and EUV irradiance sensor(X-EUVS)with the same bands as its imaging optics,which measures the solar irradiance and regularly calibrates the solar images.The radiometric calibration of X-EUVS on the ground has been completed,with a calibration accuracy of 12%.X-EUVI is loaded on the FY-3E satellite and rotates relative to the Sun at a uniform rate.Flat-field calibration is conducted by utilizing successive rotation solar images.The agreement between preliminarily processed X-EUVI images and SDO/AIA and Hinode/XRT images indicates that X-EUVI and the data processing algorithm operate properly and that the data from X-EUVI can be applied to the space weather forecast system of CMA and scientific investigations on solar activity. | Bo Chen Xiao-Xin Zhang Ling-Ping He Ke-Fei Song Shi-Jie Liu Guang-Xing Ding Jin-Ping Dun Jia-Wei Li Zhao-Hui Li Quan-Feng Guo Hai-Feng Wang Xiao-Dong Wang Yun-Qi Wang Hong-Ji Zhang Guang Zhang Zhen-Wei Han Shuang Dai Pei-Jie Zhang Liang Sun Yang Liu software engineer Peng Wang Kun Wu Chen Tao Shi-Lei Mao Gui Mei Liang Yang Li-Heng Chen Chun-Yang Han Bin Huang Yang Liu mechanical engineer Shuai Ren Peng Zhou Ze-XiWei Xiao-Xue Zhang Yue Zhang Xin Zheng Yang Wang Ya Chen Jing-Jiang Xie Fei He Qiao Song Wei-Guo Zong Xiu-Qing Hu Peng Zhang Jing-Song Wang Zhong-Dong Yang | 2022 | Light(Science & Applications)2022，11，12： | 0 |
