Cyclotron spectroscopy of electron-phonon relaxation at point contacts
Andrievskii V. V., Ass E. I., Komnik Yu. F.
Experiments reveal that the electron-phonon energy relaxation at point contacts is discrete in nature at high injection currents. It is possible to carry out a spectroscopy of the nonequilibrium electron distribution function through the use of a transverse focusing of electrons of certain energies.
