摘要

二维（2D）材料的相位工程能够探索意想不到的物理现象。在最近的一项研究中，通过自插层驱动的化学气相输运（CVT）方法合成了高结晶的6R-TaS2，在室温下具有高导电性和明显的非线性霍尔效应。这项工作表明，将异相堆叠与原子嵌入相结合为设计具有涌现特性的新材料提供了一种有效的策略。

Symmetry breaking by self-intercalation: A gateway to room temperature nonlinear Hall effects in 2D transition metal dichalcogenides

Phase engineering of two-dimensional (2D) materials enables the exploration of unexpected physical phenomena. In a recent study, highly crystalline 6R-TaS₂ was synthesized via a self-intercalation-driven chemical vapor transport (CVT) method, yielding high electrical conductivity and a pronounced nonlinear Hall effect at room temperature. This work demonstrates that combining heterophase stacking with atomic intercalation provides an effective strategy for designing new materials with emergent properties.
