Abstract: The electronic properties of random superlattices and quantum wells of lattice-matched III-V semiconductors are investigated by employing the extended empirical pseudopotential method. The model includes the important spin-orbit coupling terms in the single electron Hamiltonian. The numerical calculations are, in this case, facilitated by a highly optimises python-Fortran code, following a large basis approach. The effect of the lack of periodicity in these systems, on their electronic properties, is simulated and one possible application of the simulation results is proposed.
