Large, stable pieces of graphene produced with unique edge pattern

Graphene is a promising material for use in nanoelectronics. Its electronic properties depend greatly, however, on how the edges of the carbon layer are formed. Zigzag patterns are particularly interesting in this respect, but until now it has been virtually impossible to create edges with a pattern like this. Chemists and physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg have now succeeded in producing stable nanographene with a zigzag edge.
