Electrical Conduction in Discontinuous Films on an Insulating Substrate
Abstract
Experimental and theoretical investigation of the electrical properties of thin films during the nucleation stage of film growth was undertaken. It was found that electrostatic forces in the film can significantly influence the film resistance, nucleation rate and island size. Electrode contact effects were also found to have a large effect in measurements taken across narrow films. Experimentally it was found that a number of films investigated exhibited a reversible switching phenomena, wherein they underwent a substantial increase in conductivity when subjected to large voltages. This high conductivity then persisted to lower voltages and subsequently the film could be converted to its original condition. Previous theories of conduction in discontinuous films were considered and modified to include electrode carrier injection and substrate dielectric polarization.
