Photoinduced phase transitions and lattice deformation in 2D NbOX${}_2$ (X=Cl, Br, I)

Carmel Dansou, Charles Paillard, Laurent Bellaiche

We present a comprehensive investigation of light-induced phase transitions and strain in two-dimensional NbOX${}_2$ (X = Cl, Br, I) using first-principles calculations. In particu…
