  • Low-forward-voltage molecular rectifier
    Patent number: 7009201
    Abstract: A single molecular species having a low-forward-voltage rectifying property is provided. The molecular species is represented by the formula: CL-IL-A-IR-CR where A is a “conducting” moiety (with a relatively narrow HOMO-LUMO gap), IL and IR are each an “insulating” moiety (with a relatively wide HOMO-LUMO gap), CL is a connecting group for attachment to a first electrode, and CR is a connecting group for attachment to a second electrode. Also, a low-forward-voltage rectifying molecular rectifier is provided, comprising the molecular species attached between the two electrodes. The present teachings provide a set of design rules to build single-molecule rectifying diodes that operate at low forward and large reverse voltages. Such single-molecule rectifying diodes are useful in a variety of nano-scale applications.
