Electron trap system
Images of the electron trap architecture used by the Quantum Dynamics Unit. Top: Schematic representation of the experiment. Current of surface electrons, induced by ac voltage applied to the electrode underneath Reservoir 1, flows between Reservoirs 1 and 4 through the central microchannel, as shown by the red arrow. Middle: Cross section of the central microchannel around the gate area. Bottom: Photograph of the microchannel device on a copper sample cell, with subsequent close-up photographs of the central channel and surrounding reservoirs.
