Transport of 2D electron gas in a system of artificial scatterers: an order-disorder transition
The conductivity and negative magnetoresistance of 2D electrons in a periodic lattice and disordered lattice of antipoints have been studied experimentally. The mean free path / and the phase coherence length have been determined. The lengths / and Σφ were found to depend nonmonotonically on the degree of disorder.
