Influence of well width fluctuations on the binding energy of excitons, charged excitons and biexcitons in GaAs-based quantum wells
A. V. Filinov, C. Riva, F. M. Peeters +2
We present a first-principle path integral Monte-Carlo (PIMC) study of the binding energy of excitons, trions (positively and negatively charged excitons) and biexcitons bound to s…
Positively charged magneto-excitons in a semiconductor quantum well
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the lower singlet and triplet states of positively charged excitons (trions) confined to a single quantum well and in the presence of a perpendicular m…
Magnetic field dependence of the energy of negatively charged excitons in semiconductor quantum wells
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the spin-singlet and spin-triplet state of a negatively charged exciton (trion) confined to a single quantum well and in the presence of a perpendicula…
Excitons and charged excitons in semiconductor quantum wells
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the ground-state energy of neutral excitons and of positively and negatively charged excitons (trions) confined in a single-quantum well is presented.…
Ground state of excitons and charged excitons in a quantum well
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the ground state of a neutral exciton and of positively and negatively charged excitons (trions) in single quantum well is presented. We study the depe…
Binding energy of localized biexcitons in quantum wells
C. Riva, K. Varga, F. M. Peeters
A variational calculation of the ground state energy of a biexciton in a GaAs/AlGaAs quantum well is presented. The well width fluctuations leading to trapping of the biexcitons ar…
