WebMar 23, 2024 · Photo-induced phase transition (PIPT) provides an ultrafast, energy-efficient way for precisely manipulating the topological properties in transition-metal ditellurides, and can be used to stabilize a topological phase in an otherwise semiconducting phase. Using two-dimensional (2D) monolayer MoTe$_2$ as an example, we demonstrate that the PIPT … WebMay 17, 2024 · Abstract. We show that nonequilibrium dynamics plays a central role in the photo-induced 2H-to-1T’ phase transition of MoTe2. The phase transition is initiated by a …
