Surface Oxidation Induced Ferroelectricity and Memristor Like Conductance in Bulk T d ‐WTe 2
Tungsten ditelluride (WTe 2 ) is a unique Type‐II semimetal described by the Weyl equation to define its electronic topological band structure and known to show ferroelectricity at room temperature in the bulk phase. In this regard, two competing explanations exist: ferroelectricity arising due to intrinsic non‐c...
