Peltier cooling in molecular junctions
http://www.heatsink-guide.com/peltier.htm Web4.2 The Peltier and Thomson Effects. The Peltier effect is the reverse phenomenon of the Seebeck effect; the electrical current flowing through the junction connecting two materials will emit or absorb heat per unit time at the junction to balance the difference in the chemical potential of the two materials.

A control volume analysis shows that the cooling or heating, Q, happening at the junction is equal to Q (3 2 3 1)I (2.4) where I is the electrical current, and subscripts 1 and 2 represent Peltier coefficients for the two materials.
WebThe Peltier Module is a device with an interesting feature. When voltage is applied across its inputs, a flow of DC current is created across the junction of the semiconductors, causing a temperature difference. The side with the cooling plate absorbs heat which is then moved to the other side of the device where the heat sink is. WebDec 18, 2024 · Peltier cooling in molecular junctions.
