Paper Abstract

The chemistry of the anodic oxide of Hgl-xCdxTe is reviewed. The oxide is generally believed to contain little Hg and primarily consist of CdTeO3 with smaller amounts of HgTe03, CdTe205, HgTe205, or Te02. Consistent with the weakening Hg-Te bond strength for lower x value material, a severely defective interface between the oxide and the substrate is reported for Hg0.8Cd0.2Te, but not for Hg0.7Cd0.3Te. The detailed nature of these defects, however, remains open to debate. Models include a Hg-depleted layer in the semiconductor and an inhomogeneous oxide layer near the interface.
