Abstract

Te aggregation at the initial growth stage of CdZnTe films deposited by close-spaced sublimation (CSS) is studied with the combination of energy dispersive spectroscopy (EDS) and high resolution transmission electron microscopy (TEM). Te atoms aggregate in the form of Terich amorphous layers, and then these layers grow into stoichiometric and crystalline compounds through interdiffusion as the films thickened. Te aggregation is led by the high dissociation energy of Te-Te bond and the less volatile nature of Te 2 molecules than Cd and Zn molecules absorbed on the substrate.
