ABSTRACT:
A method of making a photoconductive coating of the type which comprises a crystalline layer of wholly inorganic material on a suitable substrate for use as an electrophotographic member, said method including the steps of depositing the coating in a vacuum chamber by sputtering with R.F. energy in such a manner that the deposit is crystalline, with the individual crystals oriented substantially vertically, the size of the crystals being uniform and hexagonal in configuration and of the order of 700 to 800 Angstroms in diameter and with a barrier layer coating on the surface that is of extreme resistivity, each crystal acting independently as an independent field domain, the crystal length normal to the substrate being the same as the coating thickness and the deposit evidencing single crystal configuration in response to diffraction pattern measurements. Background gas, including minute measured quantities of oxygen, being introduced during the sputtering and permitted to react with the surface of the sputtered coating.
