Better together: graphene-nanotube hybrid switches

Graphene has been called a wonder material, capable of performing great and unusual material acrobatics. Boron nitride nanotubes are no slackers in the materials realm either, and can be engineered for physical and biological applications. However, on their own, these materials are terrible for use in the electronics world. As a conductor, graphene lets electrons zip too fast—there's no controlling or stopping them—while boron nitride nanotubes are so insulating that electrons are rebuffed like an overeager dog hitting the patio door.
