The nexus between negative charge-transfer and reduced on-site Coulomb energy in a correlated topological metal CoTe${}_2$

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

The layered $3d$ transition metal dichalcogenide (TMD) CoTe${}_2$ is a topological Dirac Type-II metal. However, the Co $3d$-bands in CoTe${}_2$ do not exhibit the expected correlation…
