Author(s): Nicola Paradiso, Stefan Heun, Stefano Roddaro, Davide Venturelli, Fabio Taddei, Vittorio Giovannetti, Rosario Fazio, Giorgio Biasiol, Lucia Sorba, and Fabio Beltram We demonstrate an innovative quantum Hall circuit with variable geometry employing the movable electrostatic potential induced by a biased atomic force microscope tip. We exploit this additional degree of freedom to identify the microscopic mechanisms that allow two co-propagating edge channels to e... [Phys. Rev. B 83, 155305] Published Fri Apr 08, 2011
