Pressure-induced metallization and superconducting phase in ReS 2

High-pressure physics: transitions and superconductivity of compressed ReS2 ReS2 is a unique transition metal dichalcogenide (TMD) in terms of its distorted low-symmetry structure at ambient conditions. A subject that remains elusive so far is how its structure and electronic properties respond to p...
