Comparative research on the transmission-mode GaAs photocathodes of exponential-doping structures被引量:1
《Chinese Physics B》2012年第3期268-274,共7页陈亮 钱芸生 张益军 常本康 
Project supported by the National Natural Science Foundation of China (Grant Nos. 60678043 and 60801036)
Early research has shown that the varied doping structures of the active layer of GaAs photocathodes have been proven to have a higher quantum efficiency than uniform doping structures. On the basis of our early resea...

Distribution of carriers in gradient-doping transmission-mode GaAs photocathodes grown by molecular beam epitaxy被引量:7
《Chinese Physics B》2009年第10期4541-4546,共6页张益军 常本康 杨智 牛军 邹继军 
Project supported by the National Natural Science Foundation of China (Grant Nos 60678043 and 60801036)
The gradient-doping structure is first applied to prepare the transmission-mode GaAs photocathode and the integral sensitivity of the sealed image tube achieves 1420μA/lm. This paper studies the inner carrier concent...
