Diode structures obtained by vacuum sputtering deposition of Al onto the surface of p-Cd1-xZnxTe (x=0.05) single crystals were studied. In the context of the Sah-Noyce-Shockley model for generation and recombination of charge carriers, a quantitative description of the diodes' electrical characteristics is attained.
