Features of Inelastic Interaction of X-Ray Radiation with Aligned Carbon Nanotube Films

The aligned carbon nanotube (CNT) films on silicon substrate were synthesized by a thermolysis of the organic compound with a ferrocene as a catalyst. The angular dependence of X-ray fluorescence yield consisting mainly of CK radiation for the films was measured. The model curves were calculated to reveal the effect of the film density and thickness as well as the inclusion of iron nanoparticles on the X-ray radiation yield. A comparison of experimental data for the oriented and the disoriented nanotube films showed an extra intensity in the X-ray radiation yield in the direction of the nanotube growth. An influence of the CNT film structure parameters on the intensity increase is discussed based on the experimental results and the model calculations.
