We show how to compute the eigenvalues of an anisotropic Schroedinger equation for light- and heavy-hole excitons using a simplified deltalike interaction potential. Performing the calculation with a potential appropriate to bulk GaAs crystal, we obtain the excitonic binding energies for the heavy- and light-hole excitons, with the heavy-hole binding energy greater than that for the light hole. Inversion of this order for the case of a quantum well is discussed and explained.

Abstract

We show how to compute the eigenvalues of an anisotropic Schroedinger equation for light- and heavy-hole excitons using a simplified deltalike interaction potential. Performing the calculation with a potential appropriate to bulk GaAs crystal, we obtain the excitonic binding energies for the heavy- and light-hole excitons, with the heavy-hole binding energy greater than that for the light hole. Inversion of this order for the case of a quantum well is discussed and explained.
