Thermal Conductivity in Nanoporous Gold Films during Electron-Phonon Nonequilibrium

Figure 7

TTM using k_p fit to TTR experimental data taken on a 2𝜇m Au nanoporous film with ligament thicknesses around 100 nm. The fit was achieved by iterating d, the ligament, or “nanowire” thickness. A best fit was achieved with a thermal conductivity calculated using 𝑑=162 nm, in relatively good agreement with the ligament thickness of the nanoporous Au film that was tested.
