A key aspect of conductors for integrated circuits is their ability to remove heat. Several materials are commonly used including aluminum, copper, and tungsten. Lately, silver is also being considered. Calculate the electronic thermal conductivity for each at \(298 \mathrm{~K}\) using literature values for the electrical conductivity. Define a figure of merit, \(\sigma / k\) for each conductor and compare your figure of merit with that calculated from experimental data. Does silver turn out to be the clear winner?
