The binding energy of the ground-state exciton is calculated variationally for the GaAs-(Al,Ga)As system when the band-edge configuration at the heterojunction has become staggered or ''type II.'' Anisotropy in both the hole and electron effective masses is considered and calculations are perfor...

Binding energy and dephasing of biexcitons in In0.18Ga0.82As/GaAs single quantum wells Biexciton binding energies and biexciton dephasing in In0.18Ga0.82As/GaAs single quantum wells have been measured by time-integrated and spectrally resolve... P Borri,W Langbein,JM Hvam,... - 《Physical Re...
Properties of exciton states in GaAs/AlGaAs quantum wells in the presence of a quasi-two-dimensional electron gas The changes in binding energy and oscillator strength of the exciton state due to the screening by a quasi-two-dimensional electron gas are calculated self... DV Kulakovskii,SI Gub...
Abstract The energy of a biexciton in a GaAs–Al x Ga 1−x As quantum well is calculated variationally by use of a two-parameter trial wave function. The calculated binding energy, relative to two well-separated excitons, is greater than that given previously by Kleinman [Phys. Rev. B...
The binding energy of an exciton bound to a neutral donor (${\mathrm{D}}^{0}$,X) in a GaAs-${\mathrm{Al}}_{\mathrm{x}}$${\mathrm{Ga}}_{1\mathrm{$-${}}\mathrm{x}}$As quantum well is calculated variationally by using a two-parameter wave function. There is no artificial ...

The binding energy ofa biexciton in GaAs quantum-well wires is calculated variationally by use of a two-parameter trial wavefunction and a one-dimensional equivalent potential model. There is no artificial parameter added in our calculation. Our results agree fairly well with the previous results....
The theoretically predicted peaked nature of the exciton binding energy as a function of quantum-well width has been experimentally observed. The values are obtained directly from interband magneto-optical measurements and compared with calculations based on the envelope-function method. The high quality...
