Abstract

We report on a high-resolution transmission electron microscopy and energy-dispersive x-ray spectroscopy study of the microstructure of CdTe thin films epitaxially grown on single-crystal hexagonal CdS and cubic CdTe substrates. We find that the different structures of the substrates do not make a great structural difference on the grown CdTe films; i.e., on both substrates, the grown CdTe films have a cubic structure and high density of planar defects near the interface regions. At the CdTe/CdS interface, interdiffusion occurs, forming CdTe_1-x,S_x and CdS_1-xTe_x alloys. These alloys lead to significantly reduced mismatch at the interface.
