Study on Photo stability of Hydrogenated Amorphous Silicon Film

XUE Hua,YU Ji zhen,LI Yong zhong(Physics Department of Northwest Minorities Uuniversity, Lanzhou 730030 China)  
The a Si:H film have been prepared by r.f glow discharge and the illumination for the film have proceeded. The experiment results show that photocurrent and dark current decrease gradually after hydrogenated amorphous silicon is illuminated. In the early illumination, the photo and dark currents greatly decreased. Light induced effect saturate gradually with long illuminated time. The mechanism of the metastable light-induced and microscopic procedure of S W effect have been discussed.
