Abstract

The intra-and intersubband scattering rates for emission and absorption of longitudinal optical (LO) phonons by electrons confined in a cylindrical GaAs-GaAlAs quantum wire are calculated. Multiple peaks due to intersubband transitions appeared on the total scattering rate as a function of the electron energy.
