Abstract
Except for densities low enough to clearly have all carriers in the lo west subband, the ground state of a finite width quantum well is subst antially delicate to determine as it does not perturbatively come from the free carrier ground state. We show that finite momentum transfer Coulomb excitations can generate an instability each time the carrier density gets close to a threshold for new subband occupation. (C) 1997 Elsevier Science Ltd.
