Scientists have created a new type of room-temperature tunnel device structure in which the tunnel barrier and transport channel are made of the same material, graphene. Such functionalized homoepitaxial structures provide an elegant approach for realization of graphene-based spintronic, or spin electronic, devices.

The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this combination of zero and one-dimensional semiconductor structures with two-dimensional graphene is a great catalyst for many chemical reactions.
