Summary on Grant Application Form |
|
We will investigate the electrical properties of nanostructures formed from doped fullerenes and transition metal clusters. A scanning tunnelling microscope (STM) operating in ultra-high vacuum will be used to fabricate the fullerene nanostructures through molecular manipulation. A molecule of particular interest is the doped fullerene C59N which we have found may be deposited and manipulated on a surface as a free radical monomer. The transition metal clusters will be deposited using either a gas aggregation source or by direct growth on hydrogen passivated Si using the Volmer-Weber growth mode. To attach contacts to these nanometre scale objects we intent to build on the techniques we have recently developed in which ion implanted and metallic marks may be formed on clean silicon surfaces. Following fabrication the electrical characteristics of these structures will be investigated. A novel size-dependent magnetic response is expected for the transition metal clusters. For the fullerenes we will focus on the differences between the conductivity of individual molecules and molecular nanostructures formed from doped and undoped fullerenes.
