Синтез И Оценка Распределения Диаметров Углеродных Нанотрубок В Вертикально Ориентированном Массиве

Abstract

Vertically aligned carbon nanotubes arrays were synthesized via catalytic chemical vapor deposition technique. An opportunity to decreasing of acetylene as a carbon precursor contain down to 0.2% was demonstrated. An iron acetate as an alternative catalyst was proposed. Diameters of carbon nanotubes were estimated by them Raman spectra. Considering resonant behavior of radial breathing modes and them significant environment influencing, an approach based on а profile analyzing of G-band was offered to revel of nanotubes diameter distribution features.
