Description:
By studying the temperature-dependent behavior (300 K down to 43 K) of electron thermal conductivity ( κ ) in a 3.2 nm-thin Ir film, we quantify the extremely confined defect-electron scatterings and isolate the intrinsic phonon-electron scattering that is shared by the bulk Ir. At low temperatures below 50 K, κ of the film has almost two orders of magnitude reduction from that of bulk Ir. The film has ∂ κ /∂ T 〉 0, while the bulk Ir has ∂ κ /∂ T
