STM-based nanolithography of diamond-like carbon films — •Thomas Mühl — IFW Dresden, Helmholtzstr. 20, D-01069 Dresden

The spatially localized emission current of a scanning tunneling microscope tip leads to a local graphitization of diamond-like carbon thin films. Using this technique, lines and dots smaller than 10 nm in size can be written. Time resolved studies of the nanostructure growth under the STM tip will be presented, as well as time resolved graphitization of macroscopic areas of metal-contacted diamond-like carbon films induced by high current densities. Due to the widely different properties of diamond-like and graphite-like carbon, there are a lot of possible applications for such graphite nanostructures on diamond-like films. In addition, metal nanowires and nanodots can be produced by shadow (shallow angle) deposition on these carbon nanostructures.
