| Description: 
             This scanning electron 
            microscope (SEM) image shows a standard single- electron transistor. 
            The middle portion is the conducting island. Arrows at the right of 
            the island point to the source and drain electrodes. A third electrode 
            -- the metal across the island -- regulates electron flow from the 
            source to the drain. |
