Abstract
Electron scattering with longitudinal polar optical phonons in a quantizing magnetic field tilted to the plane of quantum well layers is studied. The expressions are derived for the electron scattering rate due to longitudinal polar optical phonon emission in a tilted quantizing magnetic field. The effect of variations in both the magnitude and orientation of the magnetic field on the electron-phonon scattering processes is studied. The different relation between the inter-subband spacing and the optical phonon energy are considered – when the inter-subband spacing is greater than, equal to, and lower than the optical phonon energy. Principal transformation of the inter-subband scattering rate dependence on the quantizing component of the magnetic field – from oscillatory to monotonic – was found to occur when inter-subband spacing comes closer to optical phonon frequency.
