Diffusion and Defect Characterization Studies of Mercury Cadmium Telluride.

摘要

This final report provides an overview of the major activities for our research program on the topic of diffusion and defect chemistry of mercury cadmium telluride (MCT; Hg(1-x)Cd(x)Te). In this study, we have measured tracer self-diffusion and interdiffusion coefficients in the MCT system. This provides a basis for proposed defect models for this system. A theoretical analysis based on the thermodynamics of diffusion led to new equations for interrelating the diffusion quantities in pseudobinary system, such as MCT. This analysis is consistent with our experimental information on diffusion in MCT. Epitaxial growth studies are also discussed. The isothermal vapor phase growth method was particularly emphasized in the present study. Crystallography. (JES)
