Previous investigators have found the specific resistance a constant for metallic films, until the thickness becomes comparable with particle dimensions, at which thickness the resistance becomes very great. Wait found the resistivity of chemically deposited silver films, whose thicknesses were greater than the above mentioned critical thickness, to be only slightly greater than that of the bulk metal. He found the Hall Effect in these films, as well as in films whose thicknesses were less than the critical thickness, to be the same as that of bulk silver. On the conception that the substance in a film consists of granules not in the intimate contact obtaining in the bulk form, these results could be accounted for. Consequently it became desirable to investigate silver films obtained by an evaporation method, in order to ascertain how they differ from chemically deposited films, and how these differences affect their properties.
