Molecular logic gate. Schematic 3D illustration of a molecular 'logic gate' using naphthalocyanine molecules that are being probed by the tip of a low-temperature scanning tunneling microscope (STM). By inducing a voltage pulse through the tip to the molecule underneath the tip, the two hydrogen atoms in the adjacent molecule (centre) change position and electrically switch the entire molecule from 'on' to 'off'. This represents a rudimentary logic-gate, an essential component of computer chips and could be the building block for computers built from molecular components. Image published in 2007. | |
