Thermoelectric Effect
The thermoelectric effect is the relationship between thermal and electric. When a temperature difference is created on both sides of the device, carriers in material diffuse from the hot side to the cold side, which results in a voltage across the device. Conversely, when a voltage is applied, heat is transferred from one side to the other, a temperature gradient is created. The thermoelectric effect generally consists of three effects, Seebeck effect, Peltier effect, and Thomason effect. The Seebeck effect is the electric potential built up across a temperature gradient. The potential difference is proportional to the temperature gradient. The Peltier effect is that when a current is sent through the device, heat is evolved at one end and absorbed at the other end. The Thomason effect describes the evolution or absorption of heat when an electric current passes through a circuit composed of a single material that has a temperature difference along its length. The thermoelectric effect in materials is often studied at various temperatures.
