IBM makes an RFIC with graphene

01/30/2014 | CNET

IBM researchers have fabricated a radio-frequency integrated circuit that has graphene field-effect transistors atop complementary metal-oxide semiconductor circuitry. The test chip was able to transmit data at 20 megabits per second. "One can envision that high-performance graphene radio-frequency circuits will be directly built on top of high-density silicon CMOS logic circuits to form an extremely low-cost, ultra-compact communication system," the researchers wrote in a paper published in the Nature Communications journal.
