چکیده انگلیسی
The electronic and optical properties of AlxIn1âxSb ternary alloys have been investigated using a pseudopotential approach within the virtual crystal approximation. The effect of alloy disorder on the studied properties has been examined and found to be weak. The extent of the direct-to-indirect band gap transition is found to occur at x = 0.73. Our results agree well with those reported in the literature. Trends in bonding and ionicity are discussed by means of the electron charge distribution. The present study may be a useful information for mid-infrared inter band cascade lasers applications and other antimonide device structures.
