Comparative study on the influence of AI component at GaAIAs layer for GaAs/A1GaAs photocathode被引量:1
《Journal of Semiconductors》2017年第8期16-21,共6页Yuan Xu Benkang Chang Xinlong Chen Yunsheng Qian 
supported by the National Natural Science Foundation of China(Nos.91433108,61301023)
We designed two transmission-mode GaAs/AIGaAs photocathodes with different AlxGa1-xAs layers, one has an AlxGal-xAs layer with the Al component ranging from 0.9 to 0, and the other has a fixed AI component 0.7. Using ...

High-Integrated-Photosensitivity Negative-Electron-Affinity GaAs Photocathodes with Multilayer Be-Doping Structures
《Journal of Semiconductors》2005年第9期1692-1698,共7页王晓峰 曾一平 王保强 朱占平 杜晓晴 李敏 常本康 
The effect of changing Be doping concentration in GaAs layer on the integrated photosensitivity for nega- tive-electron-affinity GaAs photocathodes is investigated. Two GaAs samples with the monolayer structure and th...
