论文摘要
研究了PD间计算的ERTE $ _3 $作为模型系统，以探索“交织”超导和电荷密度波（CDW）订单的效果。尽管只有在抑制CDW时出现超导性的普遍智慧，但我们提供了来自STM和AC敏感性测量的数据，这些数据显示CDW顺序和超导性之间没有直接竞争。两者在大多数插入范围内并存，在长度尺度上具有均匀的超导性，超过了超导相干长度。尽管持续的短距离CDW顺序和PD插入量增加了散射。虽然超导性对任何一个双向CDW中的局部缺陷都不敏感，但在超导状态的性质中观察到了费米级畸变的遗迹。
Pd-intercalated ErTe$_3$ is studied as a model system to explore the effect of "intertwined" superconducting and charge density wave (CDW) orders. Despite the common wisdom that superconductivity emerges only when CDW is suppressed, we present data from STM and AC susceptibility measurements that show no direct competition between CDW order and superconductivity. Both coexist over most of the intercalation range, with uniform superconductivity over length scales that exceed the superconducting coherence length. This is despite persisting short-range CDW order and increased scattering from the Pd intercalation. While superconductivity is insensitive to local defects in either of the bi-directional CDWs, vestiges of the Fermi-level distortions are observed in the properties of the superconducting state.
