Popis: Fluctuation of the cation valence state plays a crucial role in emergent quantum phenomena in correlated electron systems. Here, the authors demonstrate a valence-fluctuation-driven insulator-to-superconductor transition in the van der Waals insulator GeP as a function of hydrostatic pressure.
