Listen! It's a phase transition. The sound of a shape-memory alloy
Carlo Andrea Rozzi, Annamaria Lisotti, Guido Goldoni +1
Shape-memory alloys exhibit a solid-to-solid phase transition that involves a temperature-driven rearrangement of their crystal structure and is responsible for their remarkable pr…
Biexciton stability in carbon nanotubes
David Kammerlander, Deborah Prezzi, Guido Goldoni +2
We have applied the quantum Monte Carlo method and tight-binding modelling to calculate the binding energy of biexcitons in semiconductor carbon nanotubes for a wide range of diame…
Optimal design and quantum limit for second harmonic generation in semiconductor heterostructures
Guido Goldoni
The optimal design for infrared second harmonic generation (SHG) is determined for a GaAs-based quantum device using a recently developed genetic approach. Both compositional param…
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 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…
