ABSTRACT:
A hydrogen containing amorphous silicon photoconductive layer exhibits infrared absorption peaks between wavenumber of 2000 cm.sup.-1 where Si-H bonds are predominant and wavenumber of 2090 cm.sup.-1 where Si-H.sub.2 bonds are predominant and has an absorption coefficient ratio of the peaks of 2090 cm.sup.-1 to 2000 cm.sup.-1 of about 0.2 to 1.7. Preferably, the photoconductive layer is formed by a glow discharge decomposition and may contain small amount of oxygen and 10 to 20,000 ppm of Group IIIA impurity of the Periodic Table.
