Abstract

A photoconductive material comprises a photocarrier generating zone using a wide-band gap material and a photocarrier moving zone using an amorphous silicon material. A photocarrier generating zone including a silicon atom as a principal atom comprises an amorphous silicon which contains at least one kind of atom selected from a group including oxygen, nitrogen and carbon and also contains an atom which terminates a dangling bond of a silicon. This photoconductive material can be used for various devices because of its wide-band gap and high photosensitivity.
