Abstract

We determine the electronic structure of p-type modulation doped quantum wells by resonant Raman scattering and using self consistent envelope function calculations. We demonstrate that closely spaced electronic energy levels in wide quantum wells can be determined with high precision from resonant Raman measurements. We determine the conduction band non-parabolicity experimentally and theoretically. We show that the height of sharp resonant peaks in the Raman scattering cross section as a function of laser energy is related to the transition matrix elements and yields the Fourier components of the hole wavefunction in terms of the electron wavefunctions. The hole wavefunction determined experimentally agrees reasonably well with the results of the calculations.
