Recently there has been significant progress in assembling an array of individual carbon nanotubes (CNTs) on microfabricated electrodes using the Composite Electric-field Guided Assembly (CEGA) method. This technology allows for integrating individual nano components with micro/nano systems, and should find application in areas such as sensors and NEMS devices. For realizing this as a viable technology, it is crucial to understand the electric-field-driven flow around the nanostructures being deposited. We previously discovered that the flow patterns that are present can lead to deposition of a periodic array CNTs. Here, we present recent experimental observations and the results of modeling/simulation on the electric-field-driven flow around CNTs. The results suggest that this method of assembling nanostructures be used for integration with an accuracy approaching tens of nanometers.
