Pressure-induced metallization and 3d-like behavior in TcS 2
TcS 2 undergoes a charge transfer insulator to metal transition above 28 GPa. Here, laser annealing reveals a kinetically hindered high pressure arsenopyrite phase that is recoverable to ambient. The new phase is similar to the Mn-dichalcogenides rather than the expected Redichalcogenides and involves the formation of S–S and Tc–Tc bonds.
