Colossal Density-Driven Resistance Response in the Negative Charge Transfer Insulator MnS2

A reversible density driven insulator to metal to insulator transition in high-spin MnS 2 is experimentally observed, leading with a colossal electrical resistance drop of 10 8 Ω by 12 GPa. Density functional theory simulations reveal the metallization to be unexpectedly driven by previously unoccup...
