説明:

We report on a high-quality domain wall formed at the curved boundary of folded bilayer graphene (folded-BLG). At such 1D conducting channel, we measured a two-terminal resistance close to the quantum resistance R = e2/4h at zero magnetic field, a signature of kink states. Our experiments reveal a long-range ballistic transport regime that occurs only at the DW of the folded-BLG, while the other regions behave likely semiconductors with tunable band gap.
