Voltage Peak (IMAGE) Science China Press Caption Non-local transport measurements reveal a novel voltage peak at superconducting transition temperature in gold nanowire with superconducting W electrodes. The voltage peak appears when cooling the sample across Tc, while the peak turns into dip in the warming process. Upper inset, a scanning electron microscope image of Au nanowire contacted by two superconducting W compound electrodes in the middle and two normal Pt electrodes at the ends. Lower inset, configuration of electrodes. In fact, the detected peak is irrelevant to the current, and similar phenomena can be observed even in the absence of current.
