我们报告了低维导体中在高达 11 GPa 的压力下电荷密度波 (CDW) 形成与超导性之间的复杂竞争。随着压力增加，CDW 转变温度首先增加，然后在 2 GPa 处开始下降，并在 5 GPa 附近突然消失。另一方面，虽然超导转变温度降至 1.2 K 以下，并且在 2.5 K 以上 5 GPa 时未观察到，但超导转变从 2.5 K 开始出现，并急剧增加至 11 GPa。这是对压力引起的折返超导性的观察。结果根据 CDW 形成导致的费米面面积减小的变化进行了讨论。
We report on an intricate competition between charge density wave (CDW) formation and superconductivity under pressure up to 11 GPa in the low-dimensional conductor. As pressure increases, the CDW transition temperatureinitially increases, then begins to decrease at 2 GPa and abruptly disappears near 5 GPa. On the other hand, while the superconducting transition temperaturefalls to below 1.2 K atand is not observed at up to 5 GPa above 2.5 K, a superconducting transition emerges beginning atandincreases steeply up to 11 GPa. This is an observation of pressure-induced reentrant superconductivity. The results are discussed in terms of the change in the reduced area of the Fermi surface due to CDW formation.
