Zusammenfassung

Recent progress in the fabrication of atomically precise quantum wires and quantum dots by cleaved edge overgrowth is reviewed. This technique is based on molecular beam epitaxy along two or three directions in space and is capable of producing low-dimensional structures in which all relevant sizes are controlled on an atomic scale. Different sample structures consisting of isolated quantum dots ...
