Hgl-xCdxTe-Cr Interface Reaction

  • P. Philip (a1), A. Wall (a1), A. Franciosi (a1) and D. J. Peterman (a2)


We summarize photoemission studies using Synchrotron Radiation of the formation of the HgCdTe-Cr interface at room temperature on in situcleaved single crystal substrates. Evidence is found of a Cr-Hg exchange reaction in the subsurface region. The surface and near surface layers appear completely depleted of mercury.
