Boundary Scattering in Ballistic Graphene
Abstract
We report magnetotransport measurements in ballistic graphene/hexagonal boron nitride mesoscopic wires where the charge carrier mean free path is comparable to wire width W. Magnetoresistance curves show characteristic peak structures where the peak field scales with the ratio of cyclotron radius Rc and wire width W as W/Rc = 0.9 0.1, due to diffusive boundary scattering. The obtained proportionality constant between Rc and W differs from that of a classical semiconductor 2D electron system where W/Rc = 0.55.
