|Project Name - Nucleation properties of materials deposited onto carbon nanotubes at low temperatures|
|Description - Initial experiments have indicated that metals deposited onto carbon nanotubes at low temperatures have nucleation properties that are different from that of those evaporated onto usual “flat” substrates. In some intuitive sense this is to be expected since now the curvature of the nanotube substrate is of the order of the curvature of the deposited nanoparticle (~ 20 Å). The main goal of this project will be to increase our understanding of this problem on the nano-scale. The experimental tools that are available at Brookhaven National Laboratory for this work include transmission electron microscopy, electrical transport, and optical transmission measurements.|
