The Progresses of preparation and modification of graphene on substrate

Abstract

It is significant to prepare large area of high quality graphene for the study of the characteristics of graphene and the research of the nano-devices based on graphene. This paper summarizes the experiment progresses and mechanism of graphene grown on different substrates. Nowadays, we can obtain the large area of high quality graphene by using the methods, such as CVD, epitaxial growth, etc. The interaction between the graphene and the substrates is closely related to the mismatch of the lattice, weakness of the bonds and the transformation of the electrons, which has a great influence on geometry, energy band and the properties of electrons of the graphene. The combination of the experiment and the calculation can make deeper understanding of the mechanism of the effects between graphene and different substrates, which can be served as a guide for further study.
