Researchers at Princeton have developed a way to put transistors on a carbon substrate called graphene they say could one day replace silicon -- and lead to circuits 10 times faster than today's. Professor Stephen Chou and graduate student Xiaogan Liang are behind the research, which involves patching together tiny, 100-micrometer sections graphene together to form sheets large enough to print circuits on. Chou and Liang say the tech could immediately benefit wireless devices, resulting in lower power consumption and stronger signals in smaller devices. Optimistic estimates still have production-grade applications a couple years out, however -- looks like we're stuck with our ridiculously high-powered silicon until then.
