Electrostatic electron lens in the ballistic regime

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 electronse trajectories, in analogy with the modulation of the dielectric constant in conventional light-wave optics. © 1990 The American Physical Society.
