论文摘要
我们报告了在INAS纳米线约瑟夫森交界处观察到的半级夏皮罗步骤。我们观察了短弹道INAS纳米线约瑟夫森交界处的夏皮罗步骤，除了传统的整数步骤外，还发现了异常的半场台阶。随着连接温度的升高或传输的降低，半数步骤消失。这些实验结果与短弹道约瑟夫森连接中偏斜的当前相位关系的夏皮罗响应的数值计算非常吻合。
We report on half-integer Shapiro steps observed in an InAs nanowire Josephson junction. We observed the Shapiro steps of the short ballistic InAs nanowire Josephson junction and found anomalous half-integer steps in addition to the conventional integer steps. The half-integer steps disappear as the temperature increases or transmission of the junction decreases. These experimental results agree closely with numerical calculation of the Shapiro response for the skewed current phase relation in a short ballistic Josephson junction.
