The conductivity of samples of thin films of silver and platinum were investigated at temperatures ranging from liquid air down toward liquid helium temperature. It was found that electric field applied to the sample during deposition materially alters the characteristics of the films, making them more akin to those of thicker films. An explanation is suggested which is based on the permanent elongation of the film particles caused by an electric field.
