Description
Summary:In magnetic fields so large that all conduction electrons are in the lowest oscillator state, the time between collisions is a strong function of the magnetic field and the scattering mechanism. The galvanomagnetic effects, through their magnetic field dependences in this region provide. therefore, a sensitive tool for the study of the various scattering mechanisms. It can be established that scattering by phonons or randomly distributed ionized impurities can be described in the quantum limit by a relaxation time, for both longitudinal and transverse effects. The Hall coefficient and the transverse and longitudinal resistivities are calculated and compared for the two scattering mechanisms.
