Anisotropic electron-phonon interaction in silicon inversion layers in magnetic field

Abstract

In any 2D electron system with asymmetrical quantizing potential in the presence of a magnetic field parallel to the 2D plane the macroscopic quantum effect appears: due to anisotropic electron-phonon interaction in these systems an emf emerges for homogeneous heating of the electrons. This phenomenon is analyzed in this paper for 2D electron system in n-inversion layers on [001]-surface of silicon.
