Abstract

This study examines the effect of transverse thickness on the thermal conductivity of thin metallic films. The imposed temperature gradient is along the film and the transport of thermal energy is predominantly due to electron motion. The small size permits an evaluation of the Boltzmann equation of electron transport along with appropriate electron scattering boundary conditions. Simple expressions for the reduction of conductivity due to increased dominance of boundary scattering are presented and the results are compared with experimental data from the literature.
