Graphene nanoribbons: opening the gap

Graphene

Model of graphene structure by AlexanderAlUS.

The demand for smaller and smaller electronic devices has led to great strides towards the use of novel materials like graphene. One of the obstacles to the use of graphene is its lack of band gap, meaning it is difficult to use in digital electronics that need large current on/off ratios.

In their latest Topical Review in Journal of Physics D: Applied Physics, authors from Université Paris-Sud, Synchrotron SOLEIL, The Georgia Institute of Technology and Université Grenoble review comprehensively the large body of research into the electronic structure, fabrication methods and potential applications of graphene nanoribbons, summarising the key developments in the field towards opening a band gap without significantly affecting mobility.
