Thermoelectric power of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material. The term thermopower is a misnomer since it measures the voltage or electric field (not the electric power) induced in response to a temperature difference. This book presents current research in the study of thermoelectric power, including the thermoelectric power in quantum confined optoelectronic materials; the reliability and availability evaluation of equipment installed in thermoelectric power stations; innovations in organic-fuelled thermoelectric generators; thermoelectric water withdrawals in the U.S.; theoretical studies of the thermoelectric power of metallic complexes; and the gradient and contact theories of thermoelectricity.
