Low-energy type-II Dirac fermions and spin-polarized topological surface states in transition-metal dichalcogenide NiTe$_2$
Spin-resolved ARPES and DFT show that NiTe2 hosts a type-II Dirac semimetal state with the Dirac node about 20 meV above the Fermi energy and spin-polarized topological surface states.
