Semiconductor quantum tubes: dielectric modulation and excitonic response
David Kammerlander, Filippo Troiani, Guido Goldoni
We study theoretically the optical properties of quantum tubes, one-dimensional semiconductor nanostructures where electrons and holes are confined to a cylindrical shell. In these…
Optimization of semiconductor quantum devices by evolutionary search
Guido Goldoni, Fausto Rossi
A novel simulation strategy is proposed to search for semiconductor quantum devices which are optimized with respect to required performances. Based on evolutionary programming, a…
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…
Double photo-ionization of He near a polarizable surface
G. Goldoni
We calculate the differential cross-section of the direct double photo-ionization of He physisorbed on a polarizable surface. By including the influence of the surface potential in…
Band structure and optical anisotropy in V-shaped and T-shaped semiconductor quantum wires
G. Goldoni, F. Rossi, E. Molinari +1
We present a theoretical investigation of the electronic and optical properties of V- and T-shaped quantum wires. Valence band mixing as well as realistic sample geometries are ful…
