Abstract

The work is devoted to the study of heterostructures consisting from the graphene film covering the substrate, and a high density of graphene-like structures vertically oriented to the substrate plane and forming multilayer walls predominantly of circular shape. A technique has been developed that allows obtaining such structures from the carbon-containing atmosphere. The walls grew predominantly around the particles formed during the heat treatment of Fe/Al film pre-deposited on SiO2/Si substrate. The influence of electromagnetic radiation of visible and near-ultraviolet ranges on the conductivity of the obtained structures has been established. The dependence of their conductivity on the magnetic field has been shown, and the values of mobility µ and concentration ns of carriers have been measured.
