Abstract
An empirical formula for the binding energy of an electron‐heavy‐hole exciton is proposed which modifies the known formula for the Wannier exciton binding energy in the case when the well width is smaller than the bulk diameter of the exciton. This formula is utilized in calculations of the peak wavelengths in photoluminescence spectra which correspond to the ground‐state electron‐heavy‐hole exciton recombinations in Al0.3Ga0.7As/GaAs single quantum wells of various widths.This publication has 6 references indexed in Scilit:
