Based on the LMTO-ASA numerical calculations, we contrast the band eigensrates of the (GaAs)1(AlAs)1(001) superlatrice with those of the zincblende Ga0.5Al0.5As alloy. We find that they can be described unifiedly by the partial-wave states of the III and V group atomic planes. In this scheme, we analyze in more detial the correspondence relations of the band eigenstates of superlattice and zincblende alloy at Γ, M(X), and R(L) points. The effects of the superlattice zone folding on the eigenstates are also discussed.
