Graphene samples preparation and some possible uses in developing optical communication devices

Abstract

Graphene is a two-dimensional material which has been attracting the attention of worldwide scientific community, motivated by their optical and electronic properties. There are different methods for obtaining grapheme; however, the micromechanical exfoliation process is the simplest and it allows samples with high quality to be obtained. In this paper, the preparation process of graphene flakes by exfoliation method and their characterization by Raman spectroscopy are shown. Moreover, some possible uses of graphene flakes applied to develop optical communication high speed devices are described.
