By means of molecular beam epitaxy, x-ray diffraction, transmission electron microscopy, and in situ scanning tunneling microscopy, we successfully prepare type-II Dirac semimetal 1T−NiTe2 films and investigate their surface morphology, electronic structure, and topological characteristics on the atomic scale. Atomically flat NiTe2 films can be readily prepared on SrTiO3(001) substrates at ∼210∘C.
