A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
Graphene - a type of carbon - was discovered by Prof Sir Andre Geim and Prof Sir Kostya Novoselov in Manchester University in 2004. It is stronger than steel, but can conduct electricity and heat more effectively.
Vice-chancellor of Manchester University, Professor Colin Bailey, was part of the firm that developed the graphene light bulb. He said its creation was just the beginning for the ‘wonder material’.
