As. Plaut et al., LIGHT-SCATTERING DETERMINATION OF ELECTRON-TUNNELING GAPS IN DOUBLE-QUANTUM WELLS, Solid-state electronics, 40(1-8), 1996, pp. 291-293
Resonant inelastic light-scattering techniques have been used to measu
re directly the single-particle tunneling gap (Delta(SAS)) in AlxGa1-x
As/GaAs double quantum wells. We have observed a systematic decrease i
n Delta(SAS) with increasing height of the barrier in agreement with t
he Delta(SAS) calculated self-consistently within a Hartree approximat
ion.
