For modern semiconductor product design, reliability aspects have to be considered not only for technology process development but inevitable also during circuit design phase. Electronic design automation tools (EDA) have to support circuit designers

We present a magnetooptical study of the energy spectrum of two-dimensional electrons subjected to a perpendicular magnetic field in the presence of a square lattice of antidots. We demonstrate that commensurability features in the luminescence inten

Magnetoresistance measurements and theoretical calculations for two-dimensional electron systems under a perpendicular magnetic field are presented which illuminate transport effects due to a periodic electrostatic potential modulation. We focus on f

We study the energy-level statistics for electrons in a lateral two-dimensional superlattice in dependence on the strength of the modulation potential at a given perpendicular magnetic field. The interminiband statistics at some selected point in the

Rectangular antidot superlattices with ratios of the lattice constants ${\mathrm{a}}_{\mathrm{x}}$:${\mathrm{a}}_{\mathrm{y}}$ of 2:1 and 10:1 have been investigated by quantum transport calculations. All the features seen in a recent magnetotranspor

Magnetotransport in lateral superlattices covers a variety of apparently different physics dependent on the amplitude of the modulation potential relative to the Fermi energy ranging from the weakly modulated 2DEG to the antidot lattice. Here we inve

Magnetic band structures of an antidot superlattice in a perpendicular magnetic field are analysed with respect to signatures of quantum chaos. For an integer number of magnetic flux quanta threading a unit cell, they show up in the distribution of n

Antidot-superlattices which are formed by imposing a periodic potential on to a two-dimensional electron gas of high mobility exhibit specific transport properties due to the competition between characteristic lengths: lattice constant, Fermi wavelen

The classical dynamics of electrons in antidot superlattices subject to a perpendicular magnetic field is known to be chaotic. The quantum aspects of this system are investigated by calculating the magnetotransport properties and by studying the leve

We have performed quantum-mechanical as well as classical magnetotransport calculations for a lattice of antidots with additional barriers. Both approaches reproduce the experimentally observed well-known commensurability peaks simultaneously with a
