MBE growth, characterization, and electronic-device processing of HgCdTe, HgZnTe, related heterojunctions, and HgCdTe-CdTe superlattices. Quarterly report
A strong emphasis has been laid recently on the characterization of HgCdTe epilayers by a double x-ray rocking curve. A careful examination of what has been up to now reported is far from being conclusive. In fact, what is claimed as world record is only one particular point on a crystal. Above all, nobody has presently established a clear relationship between the FWHM of X-ray Rocking-Curve peak and the electrical characteristics of this HgCdTe layer. The author received his x-ray equipment during the Summer 87 and have started our own investigations. What we have in mind is (1) to understand the relationship between FWHM of the substrate - FWHM of the epilayer, (2) to establish a relationship between FWHM mobility and carrier lifetime for a given HgCdTe MBE layer grown under very well established growth conditions. We have already characterized numerous substrates and HgCdTe epilayers grown in the (111) orientation on CdTe and CdZnTe substrates.
