论文摘要
电子既表现为粒子又是波浪。因此，它可以以与光子相似的方式进行控制，并且可以类似地设计电子设备与基于光线的光线的兴奋最小的激发。在这里探索了支持狄拉克型物理学的系统，探索了电子波函数的分裂，重点是石墨烯，但同样适用于拓扑绝缘体，液体氦气和其他相对描述的系统中的电子状态。分析电子束 - 拼孔和超级对焦者，并通过纳米管传播，表明波形，系统几何形状和能量都需要平衡以最大程度地提高概率密度，从而使飞行电子的寿命。这些发现构成了新型量子电子光学器件的基础。
An electron behaves as both a particle and a 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.
