The Peltier effect

Thermodynamic consideration of thermoelectricity in metals was applied to the Peltier effect, like it was done recently for the Seebeck effect. The Peltier coefficient was derived from the difference in the total energy of electrons in two metals in contact: Π=ɛ0Tln(1+TΘV), where ɛ0 is the ‘universal’ sensitivity of thermocouples and ΘV is the characteristic temperature of a particular thermocouple.The Peltier and Seebeck coefficients derived from the new thermodynamic model were shown not to hold the Thomson relation exactly, but only in the low-temperature limit.
