摘要：

Polycrystalline PbSe1-xTex ingots were prepared by solid-state microwave synthesis. Thin films of PbSe1-xTex were then deposited onto clean glass substrates using vacuum evaporation technique. Their nanostructure morphologies and stoichiometric ratio were examined using scanning electron microscopy (SEM) and energy dispersive X-ray spectra (EDX). X-ray diffraction (XRD) patterns indicated that the lattice constants of PbSe1-xTex powders and thin films increased with the increasing amount of Te. From the electrical property measurements, the thin films were characterized by n-type behavior. (c) 2012 Elsevier Ltd. All rights reserved.
