Abstract

Remotely doped parabolic quantum wells have been grown by MBE using a digital alloy approach to vary the Al content in the AlGai.As system. The monitoring of the beam fluxes as well as the measured subband separations confirm the precision of our growth technique. Using a front gate electrode we can depopulate the electrical subbands. Thus we can determine experimentally the subband separations showing close agreement with the results of our self-consistent calculations.
