Abstract

We introduce an electrostatic lens for ballistic electrons in two-dimensional (2D) systems and demonstrate its focusing action in very high mobility GaAs-(AlGa)As heterostructures. This is the first refractive element for the control of 2D electrons. It exemplifies the close analogy between ballistic propagation in 2D electron systems and traditional geometrical optics.
