Due to surface and grain boundary scattering, thermal and electrical properties of gold nanofilms exhibit significant difference compared with bulk value. Gold nanofilms with thickness of 76 nm were studied in temperature range of 3~240 K. Experimental results indicate that the electrical and thermal conductivity of gold nanofilms are greatly reduced compared to the bulk value. It different from bulk to thermal conductivity while is consistent to electrical conductivity with temperature change. Lorenz number of gold nanofilms is higher than the corresponding bulk value, which indicates Wiedemann-Franz law is inapplicable in gold nanofilms.
