Observation of highly anisotropic bulk dispersion and spin-polarized topological surface states in CoTe2

Atasi Chakraborty, Jun Fujii, Chia-Nung Kuo +4

We present CoTe2 as a new type-II Dirac semimetal supporting Lorentz symmetry violating Dirac fermions in the vicinity of the Fermi energy. By combining first principle ab-initio c…
