摘要：
The calculation of the electronic energy levels of n-type delta-doped quantum wells in a GaAs matrix is presented. The effects of hydrostatic pressure on the band structure are taken into account specially when the host material becomes an indirect gap one. The results suggest that under the applied pressure regime the GaAs can support two-dimensional conduction channels associated to the delta-doping, with carrier densities exceeding 10(13) cm(-2)
