Abstract
We present surface analysis of close-spaced sublimated (CSS) CdTe after various pre-contact treatments. Our methods include Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS), and grazing-incidence x-ray diffraction (GI-XRD). XPS and GI-XRD analyses of the surface residue left by our solution-based CdCl2 treatment do not indicate the presence of a significant amount ofCdCl2. In addition, the solubility properties and relatively high thermal stability of the residue suggest the presence of the oxychloride Cd3Cl2O2 rather than CdCl2 as the major chlorine-containing component. Of the methods tested for their effectiveness in removing the residue, only HNO3 etches removed all detectable traces of chlorine from the surface.
