| Quantum interference Hall effect in nanopatterned two-dimensional electron gas systems (2009) | |||||||||||
Abstract | |||||||||||
| We show that in mesoscopic two-dimensional electron gas systems, quantum interference caused by predesigned nanopatterns can enhance the Hall effect by up to 500%. A quality factor Q is defined which optimizes the ratio of the Hall voltage to longitudinal voltage. Genetic algorithm and the Landauer-Büttiker formalism were used to search for the potential configuration that can achieve a large Q. We propose some realistic nanopatterns to realize this effect. | |||||||||||
