    Size Effects on Thermal Properties of Thin Metal Films With Rough Surfaces by C. R. Tellier

    Published 1990-01-01
    “…By calculating the effects of electronic scattering at rough surfaces by means of a combined Soffer-Cottey model, general theoretical expressions for the size effects in thermal properties of thin metal films are proposed. Simple analytical expressions for the thermoelectric power, Sf, and the thermal conductivity, ℒf, are given under the assumption that the energy dependence of the electronic relaxation time in bulk material may be written in the form τo∼Wm . …”
