Ballistic electron emission microscopy (BEEM) was used to study laterally patterned GaAs/Al x Ga 1-x As heterostructures. The measurements were carried out at room temperature in air as well as in liquid helium. Wet chemically etched quantum wires were identified both in topographic and BEEM current
