| Abstract(in English) | We present a zero-crossing Shapiro step generated in an asymmetric and nonhysteretic two-junction superconducting quantum interference device (SQUID) driven by one sinusoidal RF signal. The operation is based on the imbalanced evolution of the junction phases due to the tilted interference diagrams. A test circuit was designed and fabricated using 2.5kA/cm^2 Nb/AlO_x/Nb junction technology. Under irradiation of a 10GHz RF signal, we confirmed a Shapiro step crossing the zero-current axis at the voltage position of the 1st order. The polarity of the step voltage was switched by a DC control flux to the SQUID loop. Numerical current-voltage curves agreed with the experimental results quantatively. |
