Deskripsi
Monolayer transition metal dechalcogenides are a promising platform to study the interplay of low-dimensionality and electron correlations. Here, the authors report a Mott insulator state in monolayer 1T-TaSe2, that survives far above room temperature and is robust against external perturbations.
