Abstract
Accurate atomic scale structure is of importance for revealing the still mysterious electronic phase transitions in a famous 2D metal, 2H-NbSe2. In this work, the electric field gradients (EFGs) of 2H-NbSe2at Nb sites in the normal state were investigated by93Nb nuclear magnetic resonance spectroscopy in combination with first-principles computations. The previousT3/2and linearTmodels for describing the temperature dependent EFGs were tested and discussed according to our measured and theoretically computed EFG data in this two-dimensional metal.
