Abstract. In
recent time, the graphene monolayer is a widely used functional material in
various devices of nano- and optoelectronics. It is known that the kinetics of
metal growth on graphene surface can significantly differ from the growth on a
conventional substrates (Si, glass), which can be a restriction for the fabrication
of continuous thin metal films. Therefore, the study of the growth processes of
thin films of metal on graphene and the study of their properties are important
for the development of graphene-metal multilayer structures fabrication. In
this paper, we study the optical, electrical properties and structural morphology
of thin copper films on graphene and compare them with copper films of the same
thickness on glass substrate. It was shown that the growth of copper on
graphene leads to the formation of nanoparticles, which size can be controlled
by the modification of substrate temperature. In this paper we also demonstrate
the method of deposition of continuous thin copper films on graphene.
Key words: thin films, graphene, dielectric permittivity, ellipsometry.
