METHOD OF FABRICATING A COMPOSITE TRIGONAL SELENIUM PHOTORECEPTOR

摘要

A method of making a photosensitive imaging device which comprises; vacuum evaporating a thin layer of vitreous selenium over a layer of electrically active organic material which is contained on a supporting substrate, forming a relatively thin layer of electrically insulating or 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.
