Controlled Deposition and Alignment of Single Walled Carbon Nanotubes (LAR-16499)

Carbon nanotubes (CNTs) offer great potential for advanced sensing devices due to their unique electronic transport properties. However, a significant obstacle to the realization of practical CNT devices is the formation of controlled, reliable and reproducible CNT to metallic contacts. In this work, a procedure for the reliable and reproducible deposition and alignment of CNTs onto metallic electrodes is reported. This method uses photo and electron beam lithography to pattern simple Cr/Au thin film circuits on oxidized Si substrates. The application of this process should help to overcome some of the obstacles in the path towards practical CNT device development.
