摘要：

A method for calculating the electronic structure of the quaternary alloy GaxIn1-xAsyP1-y is presented. We have used the empirical pseudopotential method coupled with the virtual crystal approximation, which incorporates the compositional disorder as an effective potential. The electronic structure are studied for GaxIn1-xAsyP1-x(x = 0.5; y = 0.5) and GaxIn1-xAsyP1-y lattice matched to InP as well as GaAs. Good agreement with experiment is obtained for the calculated values of the direct energy gap and the bowing parameter at the Gamma point of the InP-lattice-matched quaternary alloy.
