A University of Central Florida professor is part of a research team that developed a graphene-based transistor that could someday lead to computers that are a thousand times faster and use a hundredth of the power.
Ryan M. Gelfand, an assistant professor in CREOL, The College of Optics & Photonics, was a graduate student at Northwestern University when he began researching the concept with fellow grad student Joseph Friedman, who is now an assistant professor at the University of Texas at Dallas.
Traditional silicon-based transistors revolutionized electronics with their ability to switch current on and off. By controlling the flow of current, transistors allowed the creation of smaller radios, televisions and computers.
As reported this month in the scholarly journal Nature Communications, Friedman, Gelfand and their fellow researchers have theorized a next-generation transistor that's based not on silicon but on a ribbon of graphene, a two-dimensional carbon material with the thickness of a single atom.
Their findings have big implications for electronics, computing speeds and big data, said Gelfand, who came to UCF in 2015.
