Real-Time Monitor and Control of MBE Growth of HgCdTe by Spectroscopic Ellipsometry

Abstract

Compositional control of Hg(1-x)CD(x)Te (MCT) during MBE growth, using a commercially viable spectroscopic ellipsometer system. The run-to-run composition reproducibility, as well as the composition uniformity during growth, should be controlled to within +/-0.001. Main Task of this Contract: Develop a knowledge base which includes a quantitative understanding of MCT growth by MBE from an optical/ellipsometric standpoint, and practical application of this understanding to effect real-time composition control. The knowledge base, which will be developed through extensive and systematic in-situ ellipsometry experiments, will be comprehensive and general enough to facilitate the transfer of this composition control technology to other MCT crystal growers
