Carbon Transistors for Post-Silicon Era
Moore's law may be running out of steam for silicon-based semiconductors, but IBM is working on the next big thing. Other alternatives might include DNA-based or liquid chemical computers.
"IBM Research demonstrated a carbon-based transistor technology that could make obsolete silicon-based CMOS chips over the next decade."
Graphene solves the No. 1 problem with today's silicon chips: Namely, that as we make them smaller and faster, they generate more and more heat. Carbon, on the other hand, harnesses quantum effects to reverse that trend, consuming less and less power as chips are made increasingly smaller and faster.
Graphene sheets also have higher carrier mobilities (the speed at which electrons are propelled by a given voltage). Carrier mobilities that are hundreds of times larger than silicon chips should translate into equally faster chip speeds for graphene.
It totally made sense. Finally, they've come up with solution for the problem silicon chips facing these days.
