“…[46] In principle, a quantum Fabry-Perot resonator can be made from graphene nano-ribbons, as discussed in ref. [27] and/or with Vakil-Engheta technology [44] and due to the small and compact size and sharp edges it will have significant benefits and very large quality factor Q. Work dealing with electron beams interacting with periodic metasurfaces with circular inclusions has been described in the excellent paper by Valagiannopoulos [46] for beam steering and may also be of interest for the reader.…”

An electron is a quantum particle and behaves as both a particle and a probability wave. On account of this it can be controlled in a similar way to a photon and electronic devices can be designed in analogy to those based on light when there is minimal excitation of the underlying Fermi sea. Here, splitting of the electron wavefunction is explored for systems supporting Dirac type physics, with a focus on graphene but being equally applicable to electronic states in topological insulators, liquid helium, and other systems described relativistically. Electron beam‐splitters and superfocusers are analysed along with propagation through nanoribbons, demonstrating that the waveform, system geometry, and energies all need to balance to maximise the probability density and hence lifetime of the flying electron. These findings form the basis for novel quantum electron optics.
