Abstract
Direct observation of the lateral current of ballistic electrons by probing with a small superconducting quantum interference device is reported. The current distribution near the end of a quantum wire shows collimation although over 30 subbands are occupied in the wire. Spreading of the collimated distribution corresponding to the transition from a ballistic to a diffusive regime is observed and is compared with simulations. © 1996 The American Physical Society.Keywords
