image: New transistor concept. Thin films made of metal nanoparticles (gray spheres) are electrically contacted by gold electrodes. The current flowing through the films (in blue) is adjustable by the voltage of a local electrode located below the film. For the characterization, needle-shaped probes are applied to the electrodes which provide the corresponding voltages and measure the current. This material relates to a paper that appeared in the July 14, 2017, issue of Science Advances, published by AAAS. The paper, by S. Willing at University of Hamburg in Hamburg, Germany, and colleagues was titled, 'Metal nanoparticle film-based room temperature Coulomb transistor.' view more
