Researchers from several universities have teamed up to develop a radical kind of transistor. Instead of using silicon, the team used graphene to build a logic gate series that uses less power but could work 1,000 times faster than current ones.
Graphene At It Again
The discovery of graphene in 2004 began a flurry of studies to isolate other two-dimensional materials. Graphene was found to be a wonder material, possessing a set of unique and remarkable properties. One of these is its ability to conduct electricity ten times better than copper, the most commonly used conductor in electronics. At room temperature, graphene is also capable of conducting electricity 250 times better than silicon, a rate faster than any other known substance.
These properties led a team of researchers from Northwestern University, The University of Texas (UT) at Dallas, University of Illinois at Urbana-Champaign, and University of Central Florida (UCF) to consider developing a graphene-based transistor. In a study published in the journal Nature Communications, the team found that a graphene-based transistor could actually work better than silicon transistors used in today’s computers.
