The E×B thermoelectric effect is based on the E×B drift, a CPT phenomenon that biases the velocity distribution of charged particles and transports them along cycloids perpendicularly to the E and B fields. This transport mechanism relies on the configuration of the electromagnetic fields, not on phonon drag and temperature difference. The resulting downstream carrier concentration produces a voltage that drives a current through a load. To close the electrical loop, the drift is turned on in the forward channel by increasing mobility and decreasing concentration, and off in the return channel by decreasing mobility and increasing concentration. Power is maximized when the Hall resistivity is matched to the sum of the Drude resistivity of the semiconductor and the equivalent load resistivity. It is also maximized at the thermodynamic threshold, where the mean free path equals the size of the cycloids. This threshold is a powerful design optimization tool.
