Role of on-site Coulomb energy and negative-charge transfer in a Dirac semi-metal NiTe${}_2$

A. R. Shelke, C. -W. Chuang, S. Hamamoto +7

Angle-resolved photoemission spectroscopy (ARPES) combined with band structure calculations have shown that the layered transition metal dichalcogenide(TMD) NiTe${}_2$ is a type-II D…
