Anneal-Induced Degradation of Amorphous Selenium Characterized by Photoconductivity Measurements
Photoconductivity measurements of amorphous selenium (a-Se) and arsenic selenide (a-As 2 Se 3 ) were carried out. Samples where annealed from 333–358 K at 5 K step for 5 minutes and the photoconductivity was measured after each annealing step. It was found that the dark current increases permanently...

however, has no noticeable change in the dark current neither in the photoconductivity ratio. Arsenic is introduced into a-Se to prevent degradation, which causes loss of image quality, but the volume must be controlled in order to maintain high photoconductivity. |
