A team of researchers led by Chen Peng from the School of Physics and Astronomy at Shanghai Jiao Tong University has recently published groundbreaking findings in Nature. The study uncovers a novel mechanism to manipulate the stability of Mott insulating states in monolayer 1T-phase transition metal dichalcogenides, such as NbSe₂, TaSe₂, and TaS₂. By fine-tuning the hybridization intensity between the d-orbitals of metal atoms and the p-orbitals of chalcogen atoms, the research reveals that the Mott insulating states in these compounds can be effectively modulated. This innovation offers a fresh perspective and platform for exploring strongly correlated electron phenomena, enhancing our comprehension of Mott insulating states and their underlying control mechanisms.
