In two-dimensional (2D) van der Waals (vdW) layered materials the application of pressure often induces a giant lattice collapse, which can subsequently drive an associated Mott transition. Here, we investigate room-temperature layer-dependent insulator-metal transition (IMT) and probable spin-crossover (SCO) in vdW magnet, FePS_3, under high-pressure using micro-Raman scattering. Experimentally obtained... Show more
