We proposed and successfully demonstrated a method to collimate electron waves propagating in a two-dimensional (2D) electron waveguide, using equivalent Snell's law for equilibrium electrons. The angular distribution of ballistic electrons emitted into a 2D electron gas formed at a high-quality AlGaAs/GaAs heterointerface was measured under a magnetic field, and an electron collimation effect was experimentally confirmed. The electron collimation can be controlled by changing the voltage applied to a collimation gate which is placed in front of the electron injector. This technique can be applied to a double-quantum-well electron-wave switch for improving the switching ratio.
