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
Lateral Nb contacts to a high-mobility two-dimensional electron gas (2DEG) in InGaAs heterostructures are studied. Below Tc of Nb a pronounced non-linearity due to the superconducting energy gap is observed in the differential resistance. The Nb/2DEG interface reveals an enhanced zero-bias resistanc
