Open AccessCloning the Dirac cones of bilayer graphene to the zone center by selenium adsorption
Dirac cones can foster extraordinary electronic effects, as exemplified by the case of graphene layers. Angle-resolved photoemission reveals that adsorption of selenium (Se) vapor on bilayer graphene creates a...

Open AccessDimensional crossover and band topology evolution in ultrathin semimetallic NiTe2 films
Nickel ditelluride (NiTe2), a recently discovered Type-II Dirac semimetal with topological Dirac fermions near the Fermi energy, is expected to exhibit strong thickness-mediated electronic tunability and intrinsi...
