摘要
We have fabricated U-shape YBa2Cu3Oy high-Tc microbridges on SrTiO3(001) substrates. The bridge is microprocessed by means of photolithography and wet etching. The fabricated configuration of the bridge is 20 μm wide, 10 μm long and 10 - 40 nm thick. Current-voltage curves show a hysteretic behavior. The junction capacitance is 0.57 pF and the IcRn product is 0.5 mV at 35 K. Shapiro steps are observed under microwave irradiation; voltage spikes are occasionally observed in current-voltage curves and are owing to the absence of the phase locking in the weak links.
