摘要：
Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) analyses of CuIn(S-1 Se-x(x))(2) thin films (x = 0.0, 0.5, 0.7 and 1.0) deposited by spray pyrolysis technique have been carried out. AES spectra of as-deposited films showed carbon, chlorine and oxygen as surface contaminants. Sputter etched spectra showed no tract of carbon and chlorine, but about 1.2% oxygen was found to be present. XPS analysis of CuIn(S1-xSex)(2) thin films prepared under optimized conditions revealed the absence of binary secondary phases. However, Cu2S or CuS was found to be secondary phase in CuIn(S0.5Se0.5)(2) thin films. (C) 2001 Scripta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
