Images of the electron trap architecture. 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, as shown by the red arrow. Middle: Cross section of the central microchannel around the electron trap area.  Bottom: Photograph of the microchannel device on a copper sample cell, with subsequent close-up photographs of the central channel and surrounding reservoirs.
