Quantum mechanical calculations of the magnetotransport coefficients of a modulated twodimensional electron gas in a perpendicular magnetic field are presented using the Kubo method. The model modulation potential used is such that the effect of the steepness of the potential and its strength on the

Magnetoresistance in a two-dimensional electron gas in a disordered lattice of antidots has been studied for the first time. Commensurability oscillations were found in an array with completely violated short range order. Not quite stochastic trajectories may be responsible for these oscillations in
A new method for array pattern synthesis in the presence of near-zone scatterers in the two-dimensional scalar case is presented. The synthesis is based on the minimization of an objecti¨e function using the simulated annealing technique. To take into account the effects of the scatterers, the physi
The magnetoresistance of electrons in a two-dimensional array of dots has been investigated. The new commensurability oscillations were found when \(2 \mathrm{R}_{L}=\mathrm{d}\) and \(2 R_{L}=\mathrm{d} / 2\). The closed electron trajectories skipping inside the dot are responsible for these oscill
