ELECTRON-LO-PHONON SCATTERING RATES IN GAAS-ALXGA1-XAS QUANTUM-WELLS
The authors calculate the electron-LO-phonon scattering rates for confined phonon modes associated to intrasubband and intersubband transitions for GaAs-AlxGa1-xAs quantum wells with finite depth.

| Summary: | The authors calculate the electron-LO-phonon scattering rates for confined phonon modes associated to intrasubband and intersubband transitions for GaAs-AlxGa1-xAs quantum wells with finite depth. The Huang and Zhu approximation for the confined LO phonon modes, based on a microscopic lattice-dynamic approach, is used and the results are compared with corresponding calculations for infinitely deep quantum wells and some experimental results. The authors found a remarkably good agreement with the experimental results. |
