Development of Milli-Kelvin Micro-Four-Point Probe Method andResearch of Monolayer Superconductors

十多年来，我们开发了一种名为“微四点探针法”的新型实验工具，并将其应用于晶体表面和单层的导电研究。在这项研究中，我们打算将该方法扩展到低至毫开尔文（0.4 K）和强磁场（高达7 T）的温度范围，以便我们可以探索单层超导/表面态超导以及表面/单层的磁输运性质的研究。

We have developed a novel experimental tool called ‘micro-four-point probe method’ for more than ten years, and applied it to studies on electrical conduction at crystal surfaces and monolayers. In this study, we have intended that the method is expended in the temperature range down to milli-Kelvin (0.4 K) and also with strong magnetic field (up to 7 T) so that we can explore the studies on monolayer superconductivity/surface-state superconductivity and the magneto-transport properties of surfaces/monolayers.
