Atomic Force and Scanning Tunneling Microscopy Studies of Single Walled Carbon Nanotubes

<p>In this diploma work I present the first experimental investigations</p><p>of carbon nanotubes at Karlstads University. Raw nanotube powder</p><p>of single walled carbon nanotubes have been dispersed primarily in</p><p>1,2-dichloroethane. The solutions have been spincoated on Au(111)</p><p>substrates. In order to determine the solubility of carbon nanotubes</p><p>in the solution the samples have been investigated in an atomic force</p><p>microscope.</p><p>Single walled carbon nanotubes deposited on a Au(111) substrate</p><p>have been investigated in a scanning tunneling microscope. Atomically</p><p>resolved STM images of single walled carbon nanotubes were obtained.</p><p>Scanning tunneling spectroscopy spectra was taken on a tube revealing</p><p>its chirality. The measured data from the nanotubes was compared to</p><p>calculations and confirmed their properties.</p><p>Dry direct contact transfers of individual single walled carbon nanotubes</p><p>have been done as a first step when trying to deposit carbon</p><p>nanotubes on reactive surfaces in ultra-high vacuum. Individual nanotubes</p><p>were found, confirming the success of dry direct contact transfer.</p>
