摘要:
Electron scattering rates due to interaction with interface phonon modes in semiconductor quantum‐well structures in a quantizing magnetic field are studied. Numerical results for scattering rates in GaAs/GaAlAs quantum wells show oscillatory behavior with magnetic field. The scattering rate due to interface phonon modes is found to decrease with the increase of well width in contrast to that seen with bulk confined phonons.
