Electron-phonon collision frequencies in aluminium; the radio frequency size effect

Abstract

The temperature dependence of radio frequency size effect (RFSE) signals was observed in aluminium using both the parallel and tilted field geometries. Electron-phonon collision frequencies were obtained for electrons on different regions of the Fermi surface and the results compared with those obtained from surface Landau level (SLL) experiments and also from theoretical calculations. Collision frequencies were obtained from orbits near the (100) and (111) limiting points of the second zone hole surface and also from orbits around the central (100) section of the zone hole surface and the (100), (111) and (110) sections of the third zone electron surface.
