Source : CDR InfoAll CPU manufacturers are actively working on solutions for the post-silicon era. One of the current alternatives is the graphene (a single atomic layer of graphite).
As a proof that this solution seems promising, IBM announced to have built and used a graphene-based transistor at 26 GHz, a new record. Of course this is an achievement, but we are still far away from the manufacturing of an entire graphene-based CPU and even more from the mass production. For sure, we might now see the way that the IT industry will follow for the next quarter of a century when the silicon era will end, if it ever happens as its end has been announced so many times
