Paper Abstract

Laser-synthesis of thin film compound semiconductors has been demonstrated to provide a very efficient way to produce high quality single phase materials for opto-electronic applications. Three semiconducting compounds may be formed in the Cu-Te system: CuTe, Cu7Te5 and Cu2Te with specific optical properties. In this work, these phases have all been laser-synthesized from a sandwich film containing a stack of elemental layers. The overall atomic proportion is closest to the aimed stoichiometry. Upon irradiation and depending on laser fluence, the compound is formed at and above a power density threshold corresponding to the abrupt melting of the film.
