ELECTRIC-FIELD-DRIVEN FLUID FLOW AROUND NANO PARTICLES

摘要

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 microano 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.
