REDUCED CARRIER COOLING AND THERMALIZATION IN SEMICONDUCTOR QUANTUM WIRES / Rota, L; Rossi, F; Goodnick, Sm; Lugli, P; Molinari, Elisa; Porod, W.. - In: PHYSICAL REVIEW. B, CONDENSED MATTER. - ISSN 0163-1829. - STAMPA. - 47:(1993), pp. 1632-1635. [10.1103/PhysRevB.47.1632]
Abstract:
By using a Monte Carlo analysis of the carrier relaxation in GaAs quantum wires following laser photoexcitation, we show that carrier cooling due to phonon emission and internal thermalization due to electron-electron interaction are significantly decreased with respect to bulk systems. This decreased thermalization is mainly attributed to the reduced efficiency of intersubband processes and to the reduced effect of electron-electron intrasubband scattering.
