DIFFUSION MECHANISMS IN MERCURY CADMIUM TELLURIDE

The key diffusion quantities for component diffusion in mercury cadmium telluride are reviewed: interdiffusion; intrinsic diffusion; and tracer self-diffusion. The interrelation between these quantities is described as well as their relation to practical diffusion problems. A review of the experimental information for these diffusion quantities is presented in the framework of diffusion theory and diffusion mechanisms. In particular, the interrelation between the fundamental diffusion quantities is used to assign diffusion values. The interpretation of marker motion and Kirkendall effect experiments is presented in the context of theory and experimental diffusion information in this system.
