Probing the spatial electron distribution in InAs nanowires by anisotropic magnetoconductance fluctuations

The authors introduce an approach to investigate the spatial distribution of the electrons in InAs nanowires using the anisotropy of low temperature magneto-conduction fluctuations. With this technique, the authors argue that the electrons responsible for transport in the nanowire are distributed through the bulk of the wire as opposed to being confined to the wire's surface.
