(color online) The top (a) and side views (b) of the geometrical structure of germanene, and the bandstructure calculated by using the primitive unit cell (c). An anitdot-patterned orthogonal nanomesh defined by A × B unit is schematically illustrated in panel (d). The antidot hole edge is passivated by hydrogen.
