Is graphene used in computers?
Basically, graphene is a 2D sheet made of carbon atoms, which has incredible properties of tensile strength and conductivity making it the thinnest but the strongest military. It conducts heat better than any other material and is also an excellent semiconductor, making it an excellent material for computers.
How is graphene made? There are different methods to produce graphene. On the same subject : How is SiC made?. One of the most well-known, used to produce monolayer graphene, is celle du dépôt chimique en phase vapeur assisted par plasma (PE-CVD). According to this process, a mélange of gas, which does not au moins un est composé de carbone, is heated until obtaining plasma.
