Germanene: the germanium analogue of graphene
The first quantum mechanical ab initio calculations on 'graphite-like' silicon and germanium sheets were performed by Takeda and Shiraishi [].They found that the configuration with the lowest energy is buckled, i.e. the two sub-lattices of the honeycomb lattice are slightly displaced with respect to each other in a direction normal to the sheet.Web
