Thermopower in discontinuous metal films

Abstract
Thermopower and conductivity data are presented for discontinuous metal films in which the concentration of 'carriers' were modified by electrostatic charging. The classic model for conduction predicts effects that are very much larger than what is observed, supporting earlier work that indicates the presence of large disorder potentials. Also in conflict with the classic model is the large thermopower that is sometimes observed in the absence of charging.
