(a) R_nl/R_sq as a function of temperature. Inset: I–V curve obtained form nonlocal measurement in single-crystal Au film devices with the central bridging wire w = 40 nm at 5 K. The linear dependency ensures the V_nl results from the applied current. Temperature dependency of R_nl (b) and R_nl/R_sq (c) for w = 40 nm and w = 50 nm.
