The effect of controllable optically-induced random anisotropic disorder on the magnetotransport in a two-dimensional electron system
Aip Conference Proceedings 772 (2005) 461-462
Abstract:
We have studied the effect of optically-induced random, anisotropic disorder on the magnetoresistance of a two-dimensional electron gas by exposing the sample to an anisotropic laser speckle pattern. Changes in the amplitude of the Shubnikov-de Haas oscillations can be explained in terms of easy and hard conductivity paths, parallel and perpendicular to the long axis of the oval speckle grains, respectively. 漏 2005 American Institute of Physics.Vortex Lattices in Rotating Atomic Bose Gases with Dipolar Interactions

Luminescence ring formation in quantum wells - A model with Coulomb interaction
Solid State Communications 134:1-2 (2005) 59-62
Abstract:
The appearance of a luminescence ring around a central illumination spot in quantum well structures is now well understood in terms of charge separation between the electron and hole gasses in the quantum well region with the ring appearing at their boundary. We propose a slightly modified model including Coulomb interaction between the electron and hole gas and their image charge. 漏 2005 Elsevier Ltd.
