Bulk 1T-NbSe2 Superconductor Stabilized by the Doped Ti-3d0 Electronic Configuration
Metastable 1T-phase transition-metal dichalcogenides host rich strongly correlated electronic phenomena, yet the synthesis of bulk 1T-NbSe2 remains a challenge. This difficulty stems from the energetic penalty associated with the octahedral coordination of Nb4+, whose 4d1 electronic configuration drives the 1T phase...
