Abstract : The technical feasibility of growing HgZnTe on CdznTe for longwave infrared applications has been demonstrated in this Phase I program. Mercury Company has developed a technique for growing reproducible large area uniform HgZnTe. The proposed research was to focus on longwave infrared (LWIR) HzZnTe, and Mercury Company routinely achieves cutoff wavelengths of 7.0 to 10.6 microns at room temperature. High quality large area Cd(0.8)Zn (0.2)Te substrates were developed by Galtech Semiconductor Materials Corporation, Utah. High resolution surface and internal IR inspection of substrates was achieved using image analysis and techniques were developed that could lead to automated inspection. In addition, SEM capabilities were developed that could lead to automated inspection of epitaxy material. Keywords: Mercury, Cadmium, Tellurium, Zinc, Liquid phase epitaxy, Tellurium melt.
