Electron optics applications of graphene

Transverse magnetic focusing has been observed in graphene and is expected to open new application area of graphene in electron-optics. In a recent report published in Nature Physics, researchers have used ambipolar nature and ballistic transport properties of graphene to study the transverse magnetic focusing effect upto room temperature.
