In2X3 (X=S, Se, Te) Semiconductor Thin Films

Abstract

Indium chalcogenide thin film semiconductor compounds In2X3 (with X being a chalcogen atom, i.e., S, Se, or Te) are important materials in many current technological applications such as solar cells, micro-batteries, memory devices, etc. This chapter reviews the recent progress in In2X3 (X = S, Se, or Te) thin film research and development, with a particular attention paid to their growth and processing methods and parameters, and the effects that these have on the films microstructure. The intimate relationship between their fabrication conditions and the resulting physico-chemical and functional properties is discussed. Finally, results pertaining to the fabrication and characterization of these thin film materials, as well as the main devices and applications based on them are also highlighted and discussed in this chapter.
