- Abstract:
- ... Graphene production is usually an expensive process, time-consuming, with low yield and often uses environmental hazardous chemicals during the process. For these reasons, many applications consider the use of graphene based materials (GBM), such as carbon thin films, instead of graphene. In this work, the aim was to produce GBM, by sputtering deposition, from a graphite target. The ability to red ...
