The rise of graphynes

Graphyne is a little known sibling of graphene. Simulations have shown that graphyne's conduction electrons travel extremely fast - as they do in graphene - but in only one direction. That property could help researchers design faster transistors and other electronic components that process one-way current. Graphyne is distinct in being composed of sp and sp2 carbon atoms, which contrasts with graphene containing only sp2 carbon. The coexistence of sp and sp2 carbons in graphyne gives rise to unique physical properties, such as high conductivity and large carrier mobility.
