In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

We have investigated mesoscopic conductance fluctuations in a GaAs quantum well with five electrically quantised two-dimensional (2D) subbands occupied. The conductance fluctuations occur even in a magnetic field parallel to the plane. We attribute the fluctuations to rapid electron-impurity scattering between different 2D subbands which leads to quasi-3D motion of electrons within the quantum well. We also report for the first time, the angular correlation of the fluctuations as the magnetic field is rotated.
