We present a combined theoretical and experimental study of the electronic and excitonic properties of GaAs-based V-grooved quantum wires as well as their dependence on external magnetic fields. We propose a numerical approach which allows us to compute electron and hole states, as well as their mutual correlation effects for realistic wire geometries. Our predictions for the optical spectra and their dependence on magnetic field are compared with several spectroscopical observations on samples grown by MBE on holographic patterns. The agreement is excellent, thus demonstrating the one-dimensional nature of the ground state exciton and the excitonic nature of the first-subband transitions in the presence of a magnetic field.

Abstract
We present a combined theoretical and experimental study of the electronic and excitonic properties of GaAs-based V-grooved quantum wires as well as their dependence on external magnetic fields. We propose a numerical approach which allows us to compute electron and hole states, as well as their mutual correlation effects for realistic wire geometries. Our predictions for the optical spectra and their dependence on magnetic field are compared with several spectroscopical observations on samples grown by MBE on holographic patterns. The agreement is excellent, thus demonstrating the one-dimensional nature of the ground state exciton and the excitonic nature of the first-subband transitions in the presence of a magnetic field.Pubblicazioni consigliate
