Silicon Wire Simulation (IMAGE) Purdue University Caption Wires just one atom tall have been created by inserting a string of phosphorus atoms in a silicon crystal by a team of researchers from the University of New South Wales, Melbourne University and Purdue University. This image from a computational simulation run of the wires shows electron density as electrons flow from left to right. The wires are 20 times smaller than the smallest wires now available and measure just four atoms wide by one phosphorus atom tall.
