Hydrogenated amorphous silicon photoconductive layer

摘要

The hydrogenated amorphous silicon photoconductive layer has an infrared spectrum containing a peak at 880.+-.10 cm.sup.-1 (intensity of this peak being referred to as I.sub.A) and a peak at 970.+-.10 cm.sup. -1 (intensity of this peak being referred to as I.sub.B) in the infrared spectrum, the ratio I.sub.A /I.sub.B, being not more than 1.0.
