Reactively sputtered a-SixGe1−x:H alloys with compositional gradient in plane of film

Abstract
A reactive sputtering technique has been utilized which enables one to deposit in a single run the alloy system a‐SixGe1−x :H over the range x=0.05–0.7 and survey IR, optical, and electrical transport properties. The technique can readily be generalized to other binary and ternary semiconductor systems.
