Abstract

AsxTe100−x chalcogenide films (where x = 30–80 at.%) were synthesized via direct interaction of arsenic and tellurium vapors into low-temperature non-equilibrium RF (40 MHz) plasma discharge at reduced pressure. Phase and structural evolution of AsxTe100−x films were implemented by gradual changing of the ratio of the initial substances in the gas phase. The dependence of the films structure, surface morphology and optical properties on phase and chemical content has been studied.
