论文摘要
最近发现的巴西自然存在的矿物质Jacutingate已证明是Kane-Mele拓扑模型的第一个实验实现。在这封信中，我们发布了一类材料$ m_2nx_3 $（$ m $ = ni，pt，pd; $ n $ = zn，cd，hg;和$ x $ = s，se，te），共享jacutingaite的关键特征，即高稳定性阶段和拓扑阶段。通过采用第一原理计算，我们广泛地表征了该类别的能量稳定性，同时显示了凯恩 - 梅尔拓扑阶段的共同出现。在这里，我们发现基于PT的材料超过了Jacutingaite令人印象深刻的拓扑间隙和较低的去角质屏障，同时保持其稳定性。
Jacutingate, a recently discovered Brazilian naturally occurring mineral, has shown to be the first experimental realization of the Kane-Mele topological model. In this letter we have unveiled a class of materials $M_2NX_3$ ($M$=Ni, Pt, Pd; $N$=Zn, Cd, Hg; and $X$=S, Se, Te), sharing jacutingaite's key features, i.e., high stability, and topological phase. By employing first-principles calculations we extensively characterize the energetic stability of this class while showing a common occurrence of the Kane-Mele topological phase. Here we found Pt-based materials surpassing jacutingaite's impressive topological gap and lower exfoliation barrier while retaining its stability.
