Summary on Grant Application Form
Single electron devices, in particular single electron transistors, are promising candidates for future nanoscale electronics owing to their very small power consumption compared to conventional electronic devices and their nanometre dimensions. Molecular recognition and self-assembly techniques offer powerful tools for the assembly of complex nanoscale molecular objects from their building blocks and the controlled integration into conventional electronic devices. I propose to design, assemble and investigate nanometre scale molecular single electron devices and to devise processes that are minimally complex to integrate these devices into conventional silicon microchips via self-assembly. Protocols to self-assemble branched, four-arm, DNA molecules onto appropriately functionalised gold electrodes of sub-100 nm separation will be developed. Regions of the molecules will be selectively rendered conducting using metallization and enzymatic polymer coating techniques. Protocols to incorporate functional elements into the branched DNA molecules to fabricate single electron devices will be developed. In addition, this arrangement will allow controlled, four-terminal conductivity measurements of short, specific sequences of DNA bases, and other incorporated molecular-scale circuit elements, and will eliminate uncertainties in the interpretation of charae transport data arising from the influence of the molecule-electrode iunction.
