Towards small switches: The relationship between molecular orbitals and the conductance of a molecular wire, composed of a nanosized graphite sheet and two gold chains, is described. Useful rules for effective quantum transport are given, and a new model for a molecular switch is proposed. As indicated in the cartoon, the zigzag edges help populate the HOMO and LUMO and thereby play an important role in conductivity.
