Specificities of growth of topological arrays of carbon nanotubes

Research results on the synthesis of carbon nanotube arrays using a combined catalyst are presented. Thanks to optimal synthesis parameters such as temperature, the reagent flow rate, the concentration and type of organometallic compound, and the composition of the catalyst film, a new synthesis method for the arrays of carbon nanotubes (CNTs) of a given topology is developed. The influence of the size effects of topological elements on the characteristics of the CNT arrays is studied. The results of a statistical analysis and research into the CNT morphology by transmission and scanning electron microscopy are shown.
