Optical excitations of a self assembled artificial ion
F. Findeis, M. Baier, A. Zrenner +4
By use of magneto-photoluminescence spectroscopy we demonstrate bias controlled single-electron charging of a single quantum dot. Neutral, single, and double charged excitons are i…
Local absorption spectra of artificial atoms and molecules
C. Simserides, U. Hohenester, G. Goldoni +1
We investigate theoretically the spatial dependence of the linear absorption spectra of single and coupled semiconductor quantum dots, where the strong three-dimensional quantum co…
Local optical spectroscopy of semiconductor nanostructures in the linear regime
O. Mauritz, G. Goldoni, E. Molinari +1
We present a theoretical approach to calculate the {\it local} absorption spectrum of excitons confined in a semiconductor nanostructure. Using the density-matrix formalism, we der…
Enhancement of Coulomb interactions in semiconductor nanostructures by dielectric confinement
G. Goldoni, F. Rossi, A. Orlandi +3
We present a theoretical analysis of the effect of dielectric confinement on the Coulomb interaction in dielectrically modulated quantum structures. We discuss the implications of…
Local Optical Spectroscopy in Quantum Confined Systems: A Theoretical Description
O. Mauritz, G. Goldoni, F. Rossi +1
A theoretical description of local absorption is proposed in order to investigate spectral variations on a length scale comparable with the extension of the relevant quantum states…
Strong exciton binding in quantum structures through remote dielectric confinement
G. Goldoni, F. Rossi, E. Molinari
We propose a new type of hybrid systems formed by conventional semiconductor nanostructures with the addition of remote insulating layers, where the electron-hole interaction is en…
