“…According to electrothermal model calculations performed with Comsol [15], resistive heating of the Au-NW at such current levels can be neglected even for significantly reduced electrical and thermal conductivities as compared to the bulk values [16]. A significant uniform heating (∆T > 200 K) is obtained, however, with assumption of very high contact resistance and/or a strongly reduced contact area, which is suggested from SEM images revealing ring-like contact area [17].…”
