β¦ Synopsis
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 disordered lattice.

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
An analysis of light scattering from a two-dimensional electron gas (2DEG) subject to a weak periodic magnetic modulation of strength B m and to a perpendicular uniform magnetic field B of arbitrary strength is presented. Raman spectra are calculated for (i) electron inter-Landau-level transitions,
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
Mesoscopic conductance fluctuations of a two-dimensional electron gas in a one-dimensional periodic array of antidots have been studied experimentally, for the first time. The fluctuations show a quasiperiodic behaviour on magnetic field, with period corresponding to the quantization of magnetic flu
Calculating the dynamical dielectric response function for a two-dimensional electron gas (2D EG) under a perpendicular magnetic field and subjected to an additional weak unidirectional periodic magnetic field within the random-phase approximation (RPA), we find that not only is the response functio
