## Abstract

In this paper, we present a simple method for calculating the valence-band structure of strained-layer quantum wells. The method consists of expanding the envelope functions of the Luttinger-Kohn Hamiltonian using a Fourier expansion. The method would be particularly useful to calculate the bound states in the quantum well for which the envelope functions decay very rapidly in the barrier regions. The effects of the spin-orbit (SO) split-off band coupling on the valence-band structure are studied within the 6 × 6 Luttinger-Kohn model. Comparison with the results obtained by the conventional finite difference method shows that the computation time required for the Fourier expansion method used in this work is of an order of magnitude less than that of the finite difference method for comparable accuracy.
