Contact interface studies of metal and carbon electrodes to germanium nanowires, carbon nanotubes and thin carbon films in associated devices

Abstract

In current state-of-the art electronic devices the electrical contact between source- and drain-electrode plays a crucial role in the performance of the nano size devices. Especially for carbon based materials such as carbon nanotubes and thin graphite layers, the electrical contacting issues become more and more critical to develop carbon based electronic devices. In the present thesis the correlation between charge- injection, of in terms of contact-resistance and specific contact resistivity into a nano-object or nanostructured material and the associated morphology of the contact- interface region, by transmission electron means, is investigated.
