Abstract

A way for mitigating internal electric field effects and improving optical performance of AlGaN quantum wells was analyzed. The model used was based on determining the quantum-well bandstructure through an iterative solution of k . p Hamiltonian and Poisson equation. The bandstructure results were used in a spontaneous emission calculation, where many-body Coulomb effects were included within the framework of the Padé approximation and quasiequilibrium condition was assumed. It was found that for low aluminium concentration, the heavy-hole band was the lowest hole band in the quantum well.
