Abstract:
A photoreceptor includes a multilayer blocking structure to reduce dark discharge of the surface voltage of the photoreceptor resulting from electron injection from an electrically conductive substrate. The multilayer blocking structure includes wide band gap semiconductor layers in alternating sequence with one or more narrow band gap blocking layers. A fabrication method of the photoreceptor includes transfer-doping of the narrow band gap blocking layers, which are deposited in alternating sequence with wide band gap semiconductor layers to form a blocking structure. Suppression of hole or electron injection can be obtained using the method.
