Description

Shubnikov-de Haas (S-dH) and Van der Pauw Hall-effect measurements on a In0.18Ga0.82As/Al0.25Ga0.75As strained single quantum well grown by molecular beam epitaxy have been performed to investigate the existence of the two-dimensional electron gas (2DEG) in the In0.18Ga0.82As single quantum well. The fast Fourier transform for the S-dH data and the observation of the quantum Hall effect clearly indicate 2DEG occupation of a subband in the In0.18Ga0.82As single quantum well. Electronic subband energy and the corresponding wavefunction in the In0.18Ga0.82As quantum well were calculated by a self-consistent method taking into account exchange-correlation effects together with strain and nonparabolicity effects
