Abstract

The x-ray diffuse scattering pattern from a commercial bulk n-type Hg0.80Cd0.20Te single crystal was measured in absolute units. Anomalous dispersion techniques near the Hg LIII edge were used to determine theintensity due to Hg interactions. Diffuse x-ray superlattice reflections are reported that are forbidden by the zinc-blende structure. The systematic absences in these peaks eliminate the possibility that they are the result of a Cu3Au ordering scheme.
