Direct Nanowiring of Carbon Nanotubes for Highly Integrated Electronic and Spintronic Devices

A feasible fabrication technique for nanomachines that are based on carbon nanotubes (CNTs) is demonstrated. Direct nanowiring of CNTs between micrometer islands is reported to have been achieved by a growth barrier technique, which prevents vertical growth of the CNTs, i.e., towards the substrate. The result is “straight” or “Y-shaped” CNT bridges between predefined electrodes (see Figure).
