IBM announced to have succeeded in reaching 100 Ghz with a graphene transistor. The transistor in question is made up of a single d' layer of carbon atoms forced into a two dimension configuration in the form of a honeycomb. It was obtained starting from simple graphite (i.e. pencil lead). This transistor exceeds by far that of traditional silicon where it is impossible to exceed 40 GHz. indeed, in Graphène, the electrons move much more quickly. Currently, this type of transistor is conceived to be used in the military communication systems. It will need a long time before the way is found to link together billions in order to produce a microprocessor.
