Two-dimensional oxygen functionalized honeycomb and zigzag dumbbell silicene with robust Dirac cones

Two-dimensional oxygen functionalized honeycomb and zigzag dumbbell silicene with robust Dirac cones

Dumbbell-like structures are recently found to be energetically favored in group IV two-dimensional (2D) materials, exhibiting rich physics and many interesting properties. In this paper, using first-principles calculations, we have investigated the oxidized form of the hexagonal honeycomb (ODB-h) a...
