From: Defect-assisted reversible phase transition in mono- and few-layer ReS2
a Schematic of the physical process underpinning the laser-induced phase transition. Femtosecond laser pulses in the near-IR range induce a phase transition from the \({\rm{T}}^{\prime\prime}\) ground state of ReS2 flakes into the \({\rm{H}}^{\prime}\) transient state manifested by a structural change. b SHG polarization-resolved intensity of \(1{\rm{T}}^{\prime\prime}\) and \(1{\rm{H}}^{\prime}\) monolayer flakes calculated using DFT. c Structural changes in the lattice symmetry upon the phase transition between \(1{\rm{T}}^{\prime\prime}\) and \(1{\rm{H}}^{\prime}\) monolayer flakes of ReS2.
