Electron spins have been predicted to align along the so-called zigzag edges of graphene (top). In reality, this perfect order is strongly affected by thermal excitations, thus imposing strict limitations on graphene-based spintronic devices. Researchers are studying the theoretical general types of spin disorder (middle and bottom) in order establish these limitations. Image credit: Oleg V. Yazyev, EPFL.

Graphene is a nanomaterial which combines a very simple atomic structure with intriguingly complex and largely unexplored physics. Since its first isolation about four years ago, researchers suggest a large number of applications for this material in anticipation of future technological innovations. Specifically, graphene is considered as a potential candidate for replacing silicon in future electronic devices.
