Abstract
Shubnikov-de Haas and Van der Pauw Hall-effect measurements on In 0.53Ga 0.47As/InP one-side-modulation-doped quantum wells grown by metalorganic chemical vapor deposition have been carried out to investigate the magnetotransport properties of an electron gas and to determine the subband energies and wave functions in a single quantum well. The Shubnikov-de Haas measurements have demonstrated the existence of a two dimensional electron gas in the In 0.53Ga 0.47As potential well. The electric subband energies, energy wavefunctions, and subband carrier densities were determined using the experimental results and a self-consistent method by taking into account the exchange-correlation effects.
