For the B terminated surface we find a low energy B {\\sigma}_1 surface state, a spz surface state, and B {\\sigma}_2 and {\\sigma}_3 quantum well states, which are 90% localized in the topmost B layer. Our results demonstrate that by charging the B atomic layer, either by changing the surface termination or through electro-chemical doping, the B {\\sigma} surface states are shifted down in energy, filled, and delocalize through hybridization as they cro","authors_text":"D.
