Effects of electron scatterings on thermal conductivity of thin metal films

Characterization and Application of Thermoelectric Nanowires

“…λ bulk = 71 W/mK at room temperature) are more than three times larger than the measured thermal conductivities of the polycrystalline Pt nanowire. This is also attributed to size effects (Ouarbya et al, 1981), mainly caused by grain boundary scattering of electrons. Fig.…”
