Direct observation of the bandwidth control Mott transition in the NiS${}_{2-x}$Se${}_x$ multiband system

H. C. Xu, Y. Zhang, M. Xu +6

The bulk electronic structure of NiS${}_{2-x}$Se${}_x$ is studied across the bandwidth-control Mott transition (BCMT) by soft X-ray angle-resolved photoemission spectroscopy. The micro…
