Show affiliationsWe have performed density functional theory calculations to show how a tungsten scanning probe can mediate the interactions between bistable Si(100) surface dimers. Interpreting the state of each dimer as a bit of information, we demonstrate the use of this mediated interaction to construct a NOR logic gate.
