Electron and positron characteristics in AlxIn1−xSb: A comparative study performed by using a pseudopotential approach

Based on a pseudopotential approach under the virtual-crystal approximation, the electron and positron band structures and their derived properties have been investigated for zinc-blende AlxIn1−xSb ternary semiconductor alloys. The effect of compositional disorder on electron and positron band structures has been examined and discussed. Moreover, the differences and the similarities between electron and positron characteristics in the material system of interest have been analyzed. The present study reveals possibilities for the investigation of the positron annihilation in AlxIn1−xSb.
