Bangkok Post – Graphene semiconductors mark new start

We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.

– This new graphene approach has a number of benefits. Power requirements are lower and the graphene structure allows for better conductivity, which means better speed. The other previously limiting factor was a heat dissipation problem. Graphene is excellent at that as well. There needs to be more development before we will see it…
