Abstract

The thermal transport in metallic thin films can be reduced by the electron scattering and there are very little available knowledge can be used to explain the mechanism. In this work, we characterized the thermal and electron transport of 3.2 nm thin gold films coated on alginate fiber by the transient electro-thermal (TET) technique. The results reveal that the thermal conductivity and electrical conductivity are reduced significantly from the respective values of bulk material by 75.9% and 93%. At the same time, the Lorenz number is calculated as 8.64 ×10-8 W O K-2 and it is three times increased from that value of bulk material. The intrinsic thermal diffusivity of alginate fiber is 3.25×10-7 m2 s-1 and the thermal conductivity is 0.51 W m-1 K-1.
