ABSTRACT:
Though a-Si:Ge has a high absorption of long wave light, so that it can be used to improve the electrophotosensitive members in the sensitivity, and it is expected as photosensitive members for printers using semiconductor laser. However, a-Si:Ge has a tendency to prevent the movement of a carrier generated to lower a sensitivity and increase a residual potential.
In the present invention, the above problems are improved by forming a depletion layer in a-Si:Ge layer to improve the mobility in forward direction of the carrier.
