Electronic properties of a graphene antidot in magnetic fields.
This paper describes unusual electronic properties of a graphene antidot created by a piecewise constant potential in a magnetic field. It reports near-complete localization of electron probability within the barrier region under some conditions and a symmetry linking antidot and dot states with identical wavefunctions but different energies, attributed to Klein tunneling. It also reports strong coupling between certain antidot states and zigzag edge states in zigzag nanoribbons and proposes experimental tests.
Key points
- The study examines graphene antidot states in the presence of a magnetic field.
- It reports that electron probability can be nearly one inside the barrier and nearly zero outside it.
- It reports a symmetry where antidot and dot states share the same wavefunction but have different energies.
- The authors attribute the reported symmetry to Klein tunneling of Dirac electrons.
- In zigzag nanoribbons, the study reports strong coupling between some antidot states and zigzag edge states.
- The paper proposes experimental tests of the reported effects.
