An Alternative Theory for Thermoelectric Power in Anderson-Mott Insulators
A new theory is developed for the thermoelectric power due to single-phonon assisted hopping. The theory relates the thermoelectric power to the average site energy on the current-carrying percolation cluster. In addition to providing new insight into this transport property, resulting formulae are easier to use than those in other theories. A calculation of the Seebeck coefficient for a nearly constant density of states, but with a small term linear in energy, yields a temperature dependence in agreement with previous theories.
