Abstract

Precursor gaseous mixtures from which to glow discharge deposit wide and narrow band gap semiconductor alloy material, said material characterized by improved photoconductivity and stability and improved resistance to photodegradation. There is also specifically disclosed a method of fabricating a narrow band gap semiconductor which method does not suffer from the effects of differential depletion of the components of the precursor gaseous mixture.
