Publication number: 20240105821Abstract: A structure of a two-dimensional material-based device having an air-gap and a method for preparing same comprises a substrate, a gate, an dielectric, a two-dimensional material-based film, and source and drain electrodes; the air-gap is formed between the two-dimensional material-based film and the side wall of the dielectric on the gate, or the air-gap is formed between the dielectric and the gate; two-dimensional material-based devices of the above structure utilize the ductility and flexibility of two-dimensional materials to reduce the coupling between the gate and the source/drain electrodes, thereby reducing the parasitic capacitance and the circuit delay; also, the structure ensures that a part of the contact region of the source and drain electrodes with the two-dimensional material can be controlled by the gate, and can thus avoid the reduction in electrical properties and keep a low resistance of the device.Type: ApplicationFiled: November 9, 2023Publication date: March 28, 2024Applicant: NANJING UNIVERSITYInventors: Xinran Wang, Dongxu Fan, Weisheng Li, Hao Qiu, Yi Shi

Patent number: 11558985Abstract: The present disclosure provides a frequency converter. The frequency converter includes a box body and a bottom box. A bottom portion of the box body is fixedly connected with a top portion of the bottom box. A top portion of a left side of the box body and a bottom portion of the left side of the box body are fixedly connected to a respective fan. A top portion of a left side of an inner wall of the box body and a top portion of the left side of the inner wall of the box body are fixedly connected to a respective annular plate. One end of an output shaft of each fan is fixedly connected to a rotating rod. One end of each rotating rod away from the fan passes through the box body and extends to an interior of the box body.Type: GrantFiled: December 18, 2020Date of Patent: January 17, 2023Assignee: CHINA UNIVERSITY OF PETROLEUM BLUE SKY (QINGDAO) PETROLEUM TECHNOLOGY CO., LTD.Inventors: Kaikai Li, Huidong Lu, Chuan Yan, Enfang Xu, Weizhong Wei, Jiasheng Zhang, Shouyuan Zhao, Liuzhu Zhang, Xinran Li, Maofeng Yang
