Abstract

Carbon nanotubes (CNTs) fabricated by thermal chemical vapor deposition (T-CVD) on GaAs microtips were investigate. Scanning electron microscope and Raman spectrum were used to characterize the properties of the nanotubes. The results showed that the GaAs tips changed into ladder-like array at high temperature and carbon nanotubes connected the neighbor GaAs with high graphite microcrystal structure. A model for the CNTs grown on GaAs microtips was also proposed. The results presented here make a significant step to the connection for micro or nano devices.
