摘要: Abstract The experiment result discloses that the sensitivity of reflection-mode NEA GaN photocathodes decrease with time after activation. Through analyzing result, it is found changes element content in surface cathodes play an important role course sensitivity. In order to explain above a model put forward. By using this model, inner mechanism leading dipoles direction because harmful gases are adsorbed photocathodes.
