Low-temperature synthesis and characteristics of fractal graphene layers

الملخص EN

Large scale fractal graphene layers are obtained by complex method of liquid phase exfoliation and self-organization.

Atomic force microscopy (AFM) is used to study the surface properties of formed layers and to assess their thickness.

Surface potential of graphene and potential transition between the graphene and substrate is measured by Kelvin probe method.

The influence of the effect of dielectric confinement on the optical properties of graphene is discussed in this work.

Raman scattering spectra were used for structural analysis and assessment of the level of defects.

Current-voltage characteristics of graphene ribbons were measured and discussed for different number of layers.
