Investigation of low-dimensional electronic systems in view of its use as quantum standards for the realization of electrical units, in particular:

  • Studies on the direct single-electron pumps with GHz frequencies
  • Preparation and optimization of quantum Hall devices, including series and parallel circuits for the realization of the unit of electrical resistance in the DC and AC field
  • Manufacture of other low-dimensional electronic systems by means of electron beam lithography and molecular beam epitaxy (MBE), including self-organized indium arsenide quantum dots
