Epitaxic Sublimation Methods for the Study of Pseudo-Binary Semiconductor Alloys.
Abstract
The first six months have seen the initiation of: research on a variety of pseudo-binary alloy materials; a series of feasibility studies on extending existing techniques never previously employed on hetero-epitaxic films to these materials as well as considering some other methods unique to film studies; a physio-chemical research program on the PbS-PbO alloy system; substantial progress in theoretical band structure calculations on end point materials (e.g. SnTe and CdS); a reformulation of the APW program to simplify future calculations. Of the five materials under study, four are being prepared routinely as epitaxic films. The evaporation system for the fifth material is rapidly approaching completion. Measurement equipment has been ordered where needed and some initial progress has been made in testing these materials. (Author)
