Optical measurements of warped valence bands in quantum wells
Abstract
The valence subband dispersion of GaAs/AlGaAs quantum wells, including warping, is measured with meV accuracy using the radiative recombination of hot electrons at neutral acceptors. The measurements are shown to be in excellent agreement with k · p calculations. Differences in calculated dispersions from using various sets of Luttinger parameters proposed in the literature are discussed. © 1994.
