Its about graphene which comes from graphite. A transistor can be made of graphene that is only 1 atom thick - that's tiny. The thought is that it could replace silicone. Graphene = more transistors = faster more advanced computer chips.
BBC: Nano switch hints at future chips
Researchers have built the world's smallest transistor - one atom thick and 10 atoms wide - out of a material that could one day replace silicon.
"It is already superior to silicon by an order of magnitude and comparable to the best samples of other materials.
"We believe we can increase this mobility of electron flow 10-fold."
