Abstract

Evidence of the adsorption of sodium dodecyl sulfate (SDS) residuals on single-walled carbon nanotubes (SWNTs) is shown using x-ray photoelectron spectroscopy. The adsorption of SDS on semiconducting SWNTs (s-SWNTs) is believed to result in deposition and alignment of s-SWNTs between predefined electrode pairs using ac dielectrophoresis. However, the presence of SDS on SWNTs degrades electrical properties of the fabricated devices. Attempts at surface cleaning, aimed at removal of the SDS residuals and formation of an improved contact between the SWNTs and the metal, are described.
