Graphene is an emerging material in the field of electronics and electrical engineering in recent years, and it is composed of only a single layer of carbon atoms, which gives it some properties that many other materials do not have. For example: high conductivity, high carrier mobility, etc. Due to its excellent performance, it is widely used in many electronic devices, among which supercomputers are a typical example. Graphene replaces silicon in supercomputers to produce transistors for use in supercomputers, and it has its own drawbacks in the process of using graphene in the process of scientists because it is not entirely advantageous. This article will discuss the advantages and disadvantages of graphene as a substitute for silicon in supercomputers. In the first part, this paper will briefly introduce how graphene is made, the sources of demand for graphene, and how graphene works instead of silicon in supercomputers, then introduce the advantages of graphene, and finally introduce the disadvantages of graphene and how to deal with it. The research in this paper will be of great value for the further research and application of graphene.
