Influence of Chamber Gas Composition on the Stability of GaAs Photocathode
Haoyu WU, Xin GUO, Linyu GAN, Peng CHEN, Zhifeng XU, Hui LIU, Gangcheng JIAO, Yufeng ZHU, and Yutian REN
GaAs photocathodes are widely used in low-light night vision owing to their high quantum efficiency and adjustable spectra. In particular, they are distinguished from multi-alkali photocathodes based on their high integration sensitivity. The negative electron affinity of GaAs photocathodes is determined through Cs, an
