Dielectrophoresis

Parallel Dielectrophoresis for carbon nanotube placement

One of the barriers to carbon nanotube electrical device fabrication is the difficulty in controllably placing the nanotubes in the correct positions to form a circuit. Laboratories have found methods to place individual nanotubes, but these methods take hours of man power for each nanotube placement, and are thus suitable only for research and are not scalable. To begin overcoming this barrier, we have sucessfully developed a parallel dielectrophoresis method that allows the precision placement of many nanotubes concurrently in an automated fashion. This is one route that could allow advancements in the field of carbon nanotube electronics.
