The talk summarizes new developments in the field of nanoelectronic devices based on carbon. Two different allotropes of carbon are at present in the focus of research, the carbon nanotubes (CNT) and graphene, a one atom thick layer of carbon.
Nanotubes are discussed as one-dimensional wires for interconnects and switching devices in electronic circuits whereas graphene seems to be an ideal two-dimensional electron system with fascinating new properties including the observation of the quantum Hall effect at room temperature. Recent experiments in this field will be presented.
