Real life RH
(table from Hemmers book). Hall effect used in Hall probes for
measuring magnetic fields. Simple Drude model not sufficient,
Hall effect with mobilities. Current jx
treated as result of both hole and electron motion.
Electrons and holes different mobilities. (compare with the drawings
for surface charges) Convention for mobilities and velocities.
Equillibrium when the currents caused
by electric + magnetic forces
cancel in y-direction. The jx must be a result
of Ex. Ex will be eliminated.
