A corner reflector of graphene Dirac fermions as a phonon-scattering sensor

Dirac fermion optics leverages p-n junctions and Klein tunnelling barriers present in materials to implement complex optical functions and devices, including reflectors, collimators, and Dirac fermion microscopes. Here, the authors fabricate Dirac fermion corner reflectors using bottom-gate-defined...
