ABSTRACT:
Ohmic contacts to p-type mercury cadmium telluride are prepared by depositing a Column IB metal on a surface of the p-type mercury cadmium telluride, depositing a buffer material on the Column IB metal, and contacting the buffer material with a bonding material which is capable of alloying with the Column IB metal. The buffer material prevents alloying between the Column IB metal and the bonding material.
