HOT-ELECTRON TRANSPORT IN QUANTUM-DOT PHOTODETECTORS
International Journal of High Speed Electronics and Systems
Employing Monte-Carlo simulations we investigate effects of an electric field on electron kinetics and transport in quantum-dot structures with potential barriers created around dots via intentional or unintentional doping. Results of our simulations demonstrate that the photoelectron capture is substantially enhanced in strong electric fields and this process has an exponential character. Detailed analysis shows that effects of the electric field on electron capture in the structures withdoi:10.1142/s0129156408005965 fatcat:guexmrcqafdqtjfy2rerkdnuba
