Amorphous selenium is one of the most promising candidates as photoconducting material for future imaging devices. It can exhibit ultra-high photosensitivity by using avalanche multiplication inside the solid. However, the requirement of high vacuum by the electron emitters prevents amorphous selenium from being a realistic imaging device in general… CONTINUE READING
