| 2 | Three-terminal germanium-on-silicon avalanche photodiode with extended p-charge layer for dark current reduction显示文摘Germanium-on-silicon(Ge-on-Si) avalanche photodiodes(APDs) are widely used in near-infrared detection, laser ranging, free space communication, quantum communication, and other fields. However, the existence of lattice defects at the Ge/Si interface causes a high dark current in the Ge-on-Si APD, degrading the device sensitivity and also increasing energy consumption in integrated circuits. In this work, we propose a novel surface illuminated Ge-on-Si APD architecture with three terminals. Besides two electrodes on Si substrates, a third electrode is designed for Ge to regulate the control current and bandwidth, achieving multiple outputs of a single device and reducing the dark current of the device. When the voltage on Ge is -27.5 V, the proposed device achieves a dark current of 100 n A, responsivity of 9.97 A/W at -40 d Bm input laser power at 1550 nm, and optimal bandwidth of 142 MHz. The low dark current and improved responsivity can meet the requirements of autonomous driving and other applications demanding weak light detection. | XIAOBIN LIU XUETONG LI YUXUAN LI YINGZHI LI ZIHAO ZHI MIN TAO BAISONG CHEN LANXUAN ZHANG PENGFEI GUO GUOQIANG LO XUEYAN LI FENGLI GAO BONAN KANG JUNFENG SONG | 2022 | Photonics Research2022，10，8： | 0 |
| 3 | CWoT-Share: Context-Based Web of Things Resource Sharing in Blockchain Environment显示文摘Web of Things(WoT)resources are not only numerous,but also have a wide range of applications and deployments.The centralized WoT resource sharing mechanism lacks flexibility and scalability,and hence cannot satisfy requirement of distributed resource sharing in large-scale environment.In response to this problem,a trusted and secure mechanism for WoT resources sharing based on context and blockchain(CWoT-Share)was proposed.Firstly,the mechanism can respond quickly to the changes of the application environment by dynamically determining resource access control rules according to the context.Then,the flexible resource charging strategies,which reduced the fees paid by the users who shared more resources and increased the fees paid by users who frequently used resources maliciously,were used to fulfill efficient sharing of WoT resources.Meanwhile,the charging strategies also achieve load balancing by dynamic selection of WoT resources.Finally,the open source blockchain platform Ethereum was used for the simulation and the simulation results show that CWoT-Share can flexibly adapt to the application environment and dynamically adjust strategies of resource access control and resource charging. | Yangqun Li Jin Qi Lijuan Min Hongzhi Yang Chenyang Zhou Bonan Jin | 2022 | Computers, Materials & Continua2022，，9： | 0 |
