Electron-phonon interaction and electron mobility in quantum-well type-II PbTe/PbS structures

Electron mobilities in PbTe layers were calculated, taking into account electron scattering by longitudinal polar optical phonons, for low-dimensional structures - multiple PbTe/PbS quantum wells, which are type-II structures. Comparison with the electron mobilities obtained from Hall coefficient and magnetoresistance investigations in undoped multiple PbTe/PbS quantum wells versus the magnetic field intensity showed good agreement between the computed and experimental results for these structures.
