The fabrication technique of local doping with a focused laser beam is employed to fabricate electronic nanostructures. Zn-doped regions are used to fabricate in-plane electron channels in a high mobility GaAs/AlGaAs heterostructure. The operation of different devices, like quantum point contacts, single electron transistors or Aharonov–Bohm rings, is demonstrated. The coplanar gate geometry ...
