Radiofrequency studies of the effects of temperature on the electrical conductivity of clean and contaminated discontinuous metal films
Abstract
A computerized a.c. technique, which represents the electrical behavior of a film by an equivalent circuit composed of frequency-independent resistors and capacitors, was used to interpret measured values of the frequency dependent resistance of films of molydenum, platinum, aluminum, and copper as a function of temperature from 150 to 400 K at various stages of exposure to carbon monoxide and oxygen. The resistance of these films was measured as a function of frequency from 0.5 to 30 Mhz and analyzed to distinguish conduction within film grains from the intergranular component.
