论文摘要
Nodal线半法（NLSS）对当前研究引起了广泛的兴趣。在大多数现有的NLS中，淋巴结线的固有特性被大大破坏，因为节点线通常会遭受不可忽略的旋转轨道耦合（SOC）引起的巨大差距。在这项工作中，我们提出了同时实现淋巴结线和电气的电子结构的拓扑结节线电气（TNLE），它为设计几乎可以免于SOC免疫的出色NLSS提供了新的见解。由于费米水平附近的状态最大程度最大，由非核心构成的间质电子贡献，因此TNLE中的节点线表现出极小的社会诱导的间隙，甚至具有重元素。尤其是，我们建议A2b（a = Ca，sr，ba; b = as，sb，bi）材料的家族是现实的tnles，具有可忽略的SOC诱导的间隙，可以作为研究TNLE的内在特性的出色平台
Nodal line semimetals (NLSs) have attracted broad interest in current research. In most of existing NLSs, the intrinsic properties of nodal lines are greatly destroyed because nodal lines usually suffer sizable gaps induced by non-negligible spin-orbit coupling (SOC). In this work,we propose the topological nodal line electrides (TNLEs), which achieve electronic structures of nodal lines and electrides simultaneously, provide new insight on designing excellent NLSs nearly immune from SOC. Since the states near the Fermi level are most contributed by nonnucleus-bounded interstitial electrons, nodal lines in TNLEs manifest extremely small SOCinduced gap even possessing heavy elements. Especially, we propose the family of A2B (A = Ca, Sr, Ba; B= As, Sb, Bi) materials are realistic TNLEs with negligible SOC-induced gaps, which can play as excellent platforms to study the intrinsic properties of TNLEs
