WebThe Hall mobility, nn, is obtained by measuring the deflection of electrons by a magnetic field while they are drifting in an electric field. Since the deflection occurs only while the electrons are quasi-free, nn is a measure of qf. Measurements of nu that have been done are for liquids of high drift mobility.
