Sažetak
The correlated $3d$ sulphide BaVS_3 exhibits an interesting coexistence of one-dimensional and three-dimensional properties. Our experiments determine the electronic band structure and shed new light on this puzzle. High-resolution angle-resolved photoemission measurements in a 4-eV wide range below the Fermi energy level uncover and investigate the coexistence of a_{; ; ; ; ; ; ; 1g}; ; ; ; ; ; ; wide-band and e_g narrow-band d-electrons that lead to the complicated electronic properties of this material. We explore the effects of strong correlations and the Fermi surface instability associated with the metal-insulator transition.
