Abstract

Magnetic electron focusing effect has been investigated by paying attention to its electron density (ns) dependence in a GaAs/AlGaAs device with multiparallel terminal. With increasing ns, a ballistic elastic scattering length increases, but a specularity at boundary decreases. In a configuration in which the electrons could enter into the extra probe between injector and collector probes, still the focusing effect is clearly observed.
