Tunable Electron Quantum Optics in Graphene Slit Junctions
This research investigates a graphene slit junction as a compact device for controlling electron transport. The study shows that this single geometry enables directional beam formation via trigonal warping, coherent interference exhibiting Aharonov-Bohm oscillations, and symmetry-controlled spin filtering using electrostatic gating. This platform is powerful for studying valley-dependent beam formation and spin effects in one structure.
