From: Temperature Dependence of Electrical and Thermal Conduction in Single Silver Nanowire

Temperature dependent thermal conductivity of the silver nanowire and the bulk silver30.
The lines connecting the experimental data are just used to guide eyes. The inset shows the linear relation between the electrical resistance and the electrical current’s square at 290 K during the thermal conductivity measurement of the silver nanowire. The fitting line is R = 53.15 + 1.833 × I2.
