It is well known that low-energy electronic excitations in graphene behave like massless Dirac fermions. Since particles (excitations) and antiparticles (holes) react oppositely to the magnetic field a magnetic field-effect transistor emerges when a carbon nanotube is placed in a perpendicular magnetic field and contacted appropriately. We calculate the current flow theoretically within a semiclassical model and simulate it numerically.
