Among the huge family of 2D materials, graphene is the superstar due to extremely high carrier mobility, high stable and outstanding mechanical strength. One typical feature of graphene is the linear band dispersion near the Fermi level, which render it possess high Fermi velocity and high carrier mobility. The families with the merit are called as Dirac materials.

From first principle calculations, we found the recent synthesized boron sheet is the stable Dirac layered materials after surface hydrogenation with high Fermi velocity, and outstanding mechanical properties. More interesting, the sheet simultaneously exhibit the phenomena of negative Poisson ratio, ferroelasticity and Dirac switch, therefore rendering borophane promising in future nanodevice application.

We also suggested that topological insulators are another family of Dirac materials due to the helical metallic edge states. With the feasible approaches, we turn graphene into strong topological insulators with large nontrivial band gaps, and demonstrated the presence of metallic edge states with 1D Dirac cones.
