Patent number: 11929446Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.Type: GrantFiled: November 8, 2022Date of Patent: March 12, 2024Assignee: CHANGCHUN UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Qun Hao, Zhipeng Wei, Jilong Tang, Huimin Jia, Lei Liao, Kexue Li, Fengyuan Lin, Rui Chen, Shichen Su, Shuangpeng Wang

Publication number: 20220114132Abstract: An artificial intelligence (AI) switch chip includes a first AI interface, a first network interface, and a controller. The first AI interface is used by the AI switch chip to couple to a first AI chip in a first server. The first network interface is used by the AI switch chip to couple to a second server. The controller receives, through the first AI interface, data from the first AI chip, and then sends the data to the second server through the first network interface. By using the AI switch chip, when a server needs to send data in an AI chip to another server, an AI interface may be used to directly receive the data from the AI chip, and then the data is sent to the other server through one or more network interfaces coupled to the controller.Type: ApplicationFiled: December 23, 2021Publication date: April 14, 2022Inventors: Xinyu Hou, Qun Jia, Weibin Liin
