Abstract

Comparative band structure calculation for Ga//0//. //5Al//0//. //5As and (GaAs)//l-(AlAs)//l (l equals 1-4) show that the effects of cation order are small. The energy bands for l equals 1 are well approximated by folding those of Ga//0//. //5Al//0//. //5As. The direct energy gap at GAMMA decreases relative to l equals 1 by 4 meV, 10 meV, and 16 meV for l equals 2,3,4, respectively.
