Placing graphene on boron nitride could significantly improve its electronic properties

Researchers from the University of Arizona, MIT and Japan's NMSI discovered that placing graphene on boron nitride (instead of the commonly used silicon dioxide) could significantly improve its electronic properties.

Boron nitride is structurally basically the same as Graphene, but it's different electronically - Graphene is a conductor and boron nitride is an insulator. Putting graphene on an insulator makes it possible to study the properties of Graphene alone.
