Abstract

The authors present recent experimental results where the evidence for the total depopulation of the first excited electric subband with pressure is demonstrated. The total electron concentration decreases at a rate of 2.7% kbar^-1, much higher than in previous experiments. The experimental situation can be fitted with the triangular-well approximation if they both assume the change with pressure of the conduction band discontinuity Delta E_c and the deepening of a deep impurity level with activation energy of the order 160 meV at zero pressure.
