Abstract
Angular distribution of emitted electrons is investigated by using the magnetic electron focusing effect in a device with probes obliquely o r vertically connected to a two dimensional electron gas, and by using low field magnetoresistance of the other device with two pairs of an emitter wire and a collector point contact. It is found that the distr ibution strongly depends on the structure just at the outlet of the wi re rather than the wire direction.
