Owing to new physical, technological, and device concepts oflow-dimensionalelectronic systems, the physics andfabrication of quasi-zero, one- and two-dimensional systemsare rapidly growing fields. The contributions presented inthis volume cover results of nanostructure fabricationincluding recently developed techniques, for example, tunneling probe techniques and molecular beam epitaxy, quantum transport including the integer and fractionalquantum Hall effect, optical and transport studies of thetwo-dimensional Wigner solid, phonon studies oflow-dimensional systems, and Si/Si Ge heterostructures andsuperlattices. To the readers new in the field this volumegives a comprehensive introduction and for the experts it isan update of their knowledge and a great help for decisionsabout future research activities.
