Abstract
The magnetotransport properties of laterally coupled self-organized InAs quantum wires are investigated, focusing on the contributions to conductivity resulting from weak localization. We demonstrate that the weak-localization correction shows a directional anisotropy equal to the anisotropy of the total conductivity; this result suggests that even for a conductivity anisotropy ratio as high as 14, the coupling between the quantum wires plays a more important role than the quasi-one-dimensional nature of the electron transport in describing the quantum-mechanical contributions due to weak localization.
