Abstract
The effect of argon ion irradiation on vacuum-evaporated as-grown Sb2Te3 fi lms in a dense plasma focused device (DPF) was studied by structural, compo sitional, and morphological analyses. The as-grown films consisted of both stoichiometric and nonstoichiometric Sb2Te3 phases with traces of Te. Ion e nergy greater than 1 MeV promoted the formation of nonstoichiometric SbxTe1 -x phase and the oxidation of Sb. Ion energy less than 1 MeV promoted the f ormation of single stoichiometric Sb2Te3 phase and a homogeneous distributi on of grain size with preferred orientation. (C) 2000 Elsevier Science Ltd.
