We studied the influence of the synthesis temperature on geometric parameters and structural perfection for vertically aligned carbon nanotubes (VACNT). We established that a synthetic temperature of 750 ◦C allows one to obtain the lowest concentration of defects in VACNT, with a diameter of 44±3 nm and a height of 80±9 nm. When temperature is increased up to 800 ◦C, an increase of the VACNT geometric dimensions was observed, which may be due to an increase in the catalytic centers (CCs) migration rate and their integration into larger centers. Also, at 800 ◦C, the concentration of defects in the nanotubes was increased due to the violation of carbon bonds during the acceleration of the acetylene desorption process from the surface of the sample.
