Abstract
We studied the wavefunctions and energy positions of the confined stat es in the valance band in an asymmetric double quantum well. We found these to be extremely sensitive to both the carrier density and the he ight of the confining barriers, which allows us to control the so-call ed 'Spin Dependent Hole Delocalization'. The theoretical results are s hown to be in excellent agreement with experiments. (C) 1997 Academic Press Limited
