THE KINECTICS OF ENERGY RELAXATION IN QUANTUM WELLS IN A QUANTIZING MAGNETIC FIELD

Tóm tắt

The kinetics of the intraband relaxation of the electron energy in the system of Landau levels lying below the the optical phonon energy is studied.  Unusual behaviour of the relaxation of electronic subsystem is found. Even though its main channel is the emission of optical phonons, the total relaxation time is several orders of magnitude higher than the characteristic scattering times on optical phonons
