Nonmonotonic Evolution and Thermodynamic Trends at Metal/(Hg,Cd)Te Interfaces: Yb/Hg0.78Cd0.22Te.

Abstract

The microscopic interaction of cleaved HgO.78Cd0.22Te surfaces with the highly reactive rare-earth Yb was studied by use of photoemission spectroscopy and synchrotron radiation. We compare the results with those of our previous investigation of Sm/(Hg,Cd)Te interface formation. Both overlayers exhibit a dramatic recovery of the Hg concentration at the interface after the first stage of metal-Te reaction. However, differences in valency between Sm and Yb develop during metal deposition and lead to differences in interface morphology. Keywords: Interface reactivity, Metal semiconductor interfaces, Mercury, Cadmium tellurides.
