ABSTRACT:
A method of making a photosensitive imaging device which comprises; vacuum evaporating a thin layer of vitreous selenium onto a supporting substrate, forming a relatively thicker layer of electrically active organic material over said selenium layer, followed by heating said device to an elevated temperature for a time sufficient to convert the vitreous selenium to the crystalline trigonal form. The imaging device is also disclosed.
