Abstract
We show that hexagonal antidot lattices of monolayer graphene exhibited the Altshuler–Aronov–Spivak (AAS) effect in low field magnetoresistance. In higher magnetic fields, Aharonov–Bohm-type oscillations were visible. The phase of AAS oscillation indicated that the chirality effect of graphene is suppressed because of inter-valley scattering due to boundary scatterings.
