CsV3Sb5压力下点接触谱数据集

CsV3Sb5是近年来发现的新型笼目结构的超导体，是理想的研究超导、电荷密度波以及拓扑性质之间关系的材料。研究此类材料有助于我们更好的理解超导机制，为高温超导的应用做出更好的理论指导。我们报道了加至2.5GPa的软点接触谱实验，结果表明了在低压0.1GPa中并未看见之前常压中存在的局部应力，而点接触所探测的超导转变也并未遵循压力下的双峰演化。拟合结果表明了有三个不同的超导能隙，其电声子耦合常数分别是小于1、2.5左右、以及大于3.5。其中，前两个较小的能隙在压力的演化中比较稳定，而较大的能隙只在临界压力P1（0.7GPa）和P2（2GPa）之间被探测到，显示出这个区域间较复杂的超导与电荷密度波的关系。其数据量为6.02MB。

CsV3Sb5 is a novel kagome-structured superconductor discovered in recent years, serving as an ideal material for investigating the interplay among superconductivity, charge density waves, and topological properties. Research on such materials helps deepen our understanding of superconducting mechanisms and provides better theoretical guidance for the application of high-temperature superconductivity. We report soft point-contact spectroscopy experiments conducted up to a pressure of 2.5 GPa. The results show that no local stress, which existed under ambient pressure, was observed at the low pressure of 0.1 GPa; additionally, the superconducting transition detected by point-contact spectroscopy does not follow the bimodal evolution under applied pressure. The fitting results reveal three distinct superconducting energy gaps, with their electron-phonon coupling constants being less than 1, approximately 2.5, and greater than 3.5, respectively. The two smaller energy gaps remain relatively stable during pressure evolution, while the larger energy gap is only detected between the critical pressures P1 (0.7 GPa) and P2 (2 GPa), indicating a relatively complex relationship between superconductivity and charge density waves within this pressure range. The total data volume of this dataset is 6.02 MB.
