Manipulation of Electron Beam Propagation by Hetero-Dimensional Graphene Junctions

exterous manipulation of light beams underpins the two defini-tive technologies of our times of in-formation age: telecommunication and the Internet. Information is processed and transferred through carefully controlled light as information carriers. In an analogy, manipulation of electron beams is expected to form the foundation for quantum infor-mation processing and quantum comput-ing in the future.1,2 Light rays in geometri-cal optics are analogous to classical trajectories of electrons, whereas electron de Broglie waves can interfere. The close re-lationship between optics and electronic
