Graphene is actually a 3-D material as well as a 2-D material, according to a new study from Queen Mary University of London.
Realising that it is a 3-D material is important for understanding its mechanical properties and for developing novel graphene-based devices.
Often hailed as a 'wonder material', graphene has the highest known thermal and electrical conductivity, is stronger than steel, light, flexible and transparent. Its uses are wide-ranging and recently it has been shown it could even act as a barrier against mosquito bites.
In this study, published in the journal Physical Review Letters, the researchers asked two fundamental questions: to what extent is graphene graphite, and what is the true thickness of graphene?
