Abstract: The paper studies the structure and chemical state of carbon nanotube-titanium oxide composites modified by ion irradiation. Scanning electron microscopy and transmission electron microscopy were used to investigate the changes in the morphology and structure of the composite after irradiation. X-ray photoelectron spectroscopy revealed changes in the chemical state of the samples, with the incorporation of nitrogen into the titanium structure. The conductivity of the composite structures was found to depend on the thickness of the titanium oxide layer and subsequent ion treatments.

Keywords: ion irradiation, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy.
