Abstract
In order to determine the diffusion coefficient of cadmium in lead tel luride D-Cd, CdTe/PbTe heterostructures were prepared by hot wall epit axy. To obtain the cadmium concentration profile, quantitative Auger e lectron spectroscopy (AES) and sputtered-neutral mass spectroscopy (SN MS) were used. The data on the cadmium depth profile were used for eva luation of the dependence of D-Cd on temperature at low temperatures ( 350-450 degrees C) in heterostructures. The data obtained for D-Cd vs. temperature are close to those calculated using the equation known fo r higher temperatures.
