Electrical Resistivity of Silver Films

Abstract

The resistivities of epitaxially grown silver films have been measured as a function of temperature from 4.2 to 295\ifmmode^\circ\else\textdegree\fi{}K. Both the temperature-independent residual resistivity and the temperature-dependent resistivity were found to increase with a decrease in the specimen thickness. The increase in the temperature-dependent part of the resistivity occurs in the temperature interval of 10 to 40\ifmmode^\circ\else\textdegree\fi{}K. It may be interpreted as being due to low-angle electron-phonon scattering, which causes a greater increment of resistivity in a film than in a bulk specimen.
