We have investigated the electronic properties of the pentanary alloy Ga x In 1– x P y Sb z As 1– y – z /InAs by means of the pseudopotential method under the virtual crystal approximation. To the best of our knowledge, such a scheme has been used for the first time for studying pentanary alloys. The composition dependence of electronic band parameters for the alloy of interest has been calculated. Our results are compared to literature data obtained by other theoretical methods.
