Research output: Contribution to journalArticlepeer-review


We investigate the effects of inelastic optical- and acoustic-phonon scattering in quasi-one-dimensional systems with up to 20 subbands. We use a direct-integration Monte Carlo method to study intersubband scattering effects when the subband spacing approaches resonance (nE being the optical-phonon energy of 36 meV). Simulations performed on first-, second-, and third-order resonant structures at temperatures ranging from 150 to 300 K reveal the appearance of dissipative transport properties. Specifically, nonlinearities in the electron distribution induce velocity fluctuations analogous to the longitudinal magnetophonon effect and generate population inversions between adjacent subbands.
