Semiconducting response in single-walled carbon nanotubes filled with cadmium chloride

Authors/others:Kharlamova, Marianna V.Kramberger, ChristianPichler, Thomas
Abstract:Here, we report on filling of single-walled carbon nanotubes (SWCNTs) with cadmium chloride by a capillary filling method. Changes in the electronic properties of the filled nanotubes were traced by multifrequency Raman spectroscopy using seven excitation laser wavelengths. A detailed analysis of the Raman response of pristine and filled nanotubes was conducted. The fitting of the Raman spectra of either type of SWCNT material allowed comparing the modifications in the electronic structure of the filled SWCNTs with certain diameters. The encapsulated cadmium chloride led to dominating semiconducting and suppressed metallic characteristics in the spectroscopic response of the filled SWCNTs.
