摘要

电子束在各向同性介质和各向同性介质之间的界面发生折射后可以被引导或准直。在这种情况下，折射可以是负的或正的，作为入射角的函数。材料参数影响转向角，而弹道电子的能量决定准直程度。

Manipulating ballistic electrons by refraction at an interface between isotropic and anisotropic media

Electron beams can be steered or collimated after refraction at an interface between an isotropic medium and an isotropic one. In this situation the refraction can be negative or positive as a function of the incidence angle. The materials' parameters influence the steering angle, whereas the energy of the ballistic electrons determines the degree of collimation.
