The scaling laws for the miniaturization of microelectronic devices
break down if the wave nature and the discrete charge of electrons dominate
the electronic properties. These quantum phenomena do not mark the end in
the miniaturization of devices but open the possibility to create new devices
with new functions where for example ballistic transport, the energy quantization
of electrons in confined structures, the electron spin, tunnel phenomena through
barriers, and single electron charging of small islands play an important role.
The talk gives an overview about the physics, technology and application of semiconductor
quantum structures and discusses some recent basic research activities in the
fascinating field of quantum information technology.
