利用低温扫描隧道显微镜/光谱仪，通过测量超导带隙底部的隧道电导并绘制其空间分布图，研究了Pb纳米超导岛结构的超导性和涡旋形成。在纳米尺度超导体中观察到了在大尺度超导体中没有观察到的特殊的涡旋聚集现象。
Using low-temperature scanning tunneling microscopy/spectroscopy, we have studied superconductivity and vortex formation on Pb nano-size superconducting island structures by measuring the tunneling conductance at the bottom of the superconducting gap and making its spatial mapping. Peculiar clustering of vortices, which is not observed in large-scale superconductors, is observed in the nanosize superconductors.
