Sub-picosecond photo-induced displacive phase transition in two-dimensional MoTe2
Abstract Photo-induced phase transitions (PIPTs) provide an ultrafast, energy-efficient way for precisely manipulating the topological properties of transition-metal ditellurides and can be used to stabilize a topological phase in an otherwise semiconducting material. Using first-principles calculations, we demonstrate that the PIPT in monolayer MoTe 2 from the semiconducting 2H phase …
