The full electronic band structure of the pentanary alloy GaxIn1-xPySbzAs1-y-z was studied using the universal tight binding (UTB) method, including the composition dependences of the energy band gap and the density of states (DOS). The lattice matching conditions for various substrates are obtained by optimizing the alloy bond length with respect to composition in comparison to the natural bond length of the substrate. The composition dependences of the principal energy band gaps [E(Γ), E(L), and E(X)] are calculated for the alloy lattice matched to different substrates.
