Synthesis of carbon nanostructures on copper films by the method of oxy-acetylene torch

Abstract

The work presents the results of experiments on the synthesis of carbon nanostructures by the method of oxy-acetylene torch on the surface of pre-deposited copper thin films. The influence of the concentration ratio of oxygen and acetylene and duration of the deposition on the structure formation was investigated. According to the analysis by Raman spectroscopy and SEM methods, the obtained samples, depending on the experimental conditions, have a different structure and morphology. As a result of the experiments, monolayer graphene, nano and micro-diamonds with well-defined crystal faces and edges were obtained, as well as carbon structures, which are nanotubes. Studies using Raman scattering and scanning electron microscopy showed that synthesis of micro-diamonds occurs under certain experimental conditions.
