Abstract

In this work the internal channels of the single-walled carbon nanotubes

(SWCNTs) were filled with cadmium chloride, cadmium bromide, and

cadmium iodide by a capillary method using melts of these salts. The

influence of incorporated chemical compounds on the electronic

properties of the carbon nanotubes was investigated by optical

absorption spectroscopy, Raman spectroscopy, near edge X-ray absorption

fine structure spectroscopy, and X-ray photoelectron spectroscopy. It

was found that there is the chemical bonding between carbon atoms of

nanotube walls and metal atoms of encapsulated CdX₂

nanocrystals. The obtained data testify acceptor doping effect of

cadmium halogenides incorporated into the SWCNT channels, which is

accompanied by the charge transfer from nanotube walls to introduced

substances.
