摘要

作为地球上最普遍的元素,碳表现出多种多样的同素异形相,极大地促进了其复杂的物理特性。最近,有报道称几种碳同素异形体在理论和实验中具有丰富的拓扑相。这项研究的重点是由 5-6-7 型 Z-ACA 碳环组成的 sp3 碳同素异形体 Z-ACA 同素异形体。据报道,这种同素异形体是一种可与金刚石媲美的超硬材料。在这项研究中,我们发现它既是受阻原子绝缘体,也是真正的切尔恩绝缘体。值得一提的是,Z-ACA 因其铰链边界态表现而呈现出非常规的体界对应关系。我们目前的研究表明,Z-ACA 是研究真实拓扑和二阶体界对应关系的合适碳相平台。

Z-ACA allotrope: a topological carbon material with obstructed Wannier charge center, real topology, and hinge states
As the most prevalent element on our planet, carbon manifests a wide variety of allotropic phases, significantly contributing to its complex physical properties. Recently, several carbon allotropes have been reported to possess abundant topological phases in theory and experiment. This work focuses on a sp3 carbon allotrope, Z-ACA allotrope, which consists of 5-6-7-type Z-ACA carbon rings. This allotrope has been reported previously as a superhard material comparable to diamond. In this study, we report that it is a candidate for both an obstructed atomic insulator and a real Chern insulator. It is worth mentioning that Z-ACA exhibits an unconventional bulk-boundary correspondence due to its hinge boundary state manifestation. Our current research indicates that Z-ACA is a suitable carbon phase platform for studying the real topology and second-order bulk-boundary correspondence.
