dc.description.abstract | The Dirac point and cones make some two-dimensional materials ( e.g., graphene, silicone and graphyne) exhibit ballistic charge transport and enormously high carrier mobilities. Here, we present a novel semimetal with triangular lattice. Metallic BeB2 monolayer could transform to a semimetal with a Dirac point at the Fermi level when the lattice parameters are isotropically compressed by about 5%, while it becomes metallic again under larger compression. The Fermi velocity of semimetallic BeB2 monolayer is 0.857 x 10(6) m s(-1), just a little smaller than that of graphene. Furthermore, it is found that uniaxial compressive strain opens a band gap in the BeB2 monolayer, while uniaxial tensile strain keeps it metallic. Our study expands the Dirac systems and provides new insight to explore novel semimetallic materials. | - |
