Solid phase recrystallization of ZnS thin films on sapphire

Abstract

High quality ZnS thin films are important for light emitting diodes based on ZnS, which is a very efficient phosphor. To improve as grown, molecular beam epitaxial, ~111!-oriented cubic ZnS films, where defects were introduced due to the large mismatch between ZnS and a sapphire substrate (;20%), the ZnS was recrystallized by annealing at temperatures in… (More)
