Subband structure and band bending in symmetric modulation-doped double quantum wells
Abstract
We have calculated the subband structure and confinement potential of modulation-doped Ga1-xAlxAs-GaAs symmetric double quantum wells a function of the doping concentration. Electronic properties of this structure are determined by solving the Schrodinger and Poisson equations self-consistently. To understand the exchange correlation potential effects on the band bending and subband populations, this potential has been included in the calculation at 0 K and, at room temperature. We find that at low doping concentrations the effect of the exchange correlation potential is more pronounced on the subband populations.
