Abstract The hydrostatic pressure effects on CdxHg1−xTe alloys have been investigated. In the relatively low pressure region, we find an anomaly in each Hall coefficient vs. pressure curve for the alloys (x〈0.09), which is attributed to the inversion of the Γ8/Γ6 energy bands. In the relatively high pressure region, the electrical resistivities of the alloy crystals (x〉0.09) show changes of three stages with increase of pressure. The crystal structures corresponding to the three stages are studied by an X-ray diffraction analysis. It is found that the crystal structure of the alloys exhibits transitions from the zinc-blende to the rock salt type and at last to the hexagonal cinnabar type.
