Abstract Single layers of Yb at the Hg/sub 1-//sub x/Cd/sub x/Te(110) interface prevent Al-Te reaction and dramatically increase the Hg concentration at the interface. Synchrotron radiation photoemission studies of the interface as a function of Al deposition show a two orders of magnitude increase in the Hg/Te core intensity ratio as a result of the interlayer-induced change in atomic interdiffusion. Calculations of thermodynamic parameters following a semiempirical alloying model suggest that other rare earths should also act as effective diffusion barriers at mercury-cadmium-telluride/reactive metal junctions.
