Abstract

It is well known that current flowing across a P-N type junction will result in a temperature gradient, known as the Peltier Effect. By the associated Seebeck Effect, this thermal gradient results in a potential difference. The thermal gradient, and the associated thermal voltage, takes time to develop. Under alternating current excitation, this could result in a thermal voltage that lags the driving signal, giving the appearance of a complex impedance. We present results from our measurements of several P, N and P-N type materials.
