Abstract
Electrostatic focusing of ballistic electrons in a high-mobility two-dimensional electron gas is discussed and experimentally demonstrated. The focusing is achieved by a spatial modulation of the electrostatic potential along the electrons’ trajectories, in analogy with the modulation of the dielectric constant in conventional light-wave optics.Keywords
