Abstract

The ternary alloys PbxCd1−xTe were prepared by the vertical Bridgman method and studied from a morphological viewpoint. The evolution of the different defects with the Pb concentration was described. For x = 0.20, strong segregation was found. A supercrystal structure, formed by alternated layers of CdTe and PbTe was encountered in the PbTe rich phase. We propose some hypothesis about the mechanism for their formation. An interpretation of the optical behavior in the 0.2–0.6 eV infrared region will be also presented.
