摘要：

We report theoretical investigations of Shapiro step formation at high microwave drive frequencies. A drive frequency equal to the gap frequency or its first subharmonic generates current-voltage characteristics that are especially well suited for Josephson voltage standards. Such drive frequencies increase the stability of the reference voltage and reduce the total number of junctions required to produce a given voltage. In contrast to conventional series-array voltage standards, the dc current bias has to be chosen on the order of the critical current.
