University of Texas at Dallas scientists are investigating how structures made from several layers of graphene stack up in terms of their fundamental physics and their potential as reconfigurable semiconductors for advanced electronics.
Graphene is a single layer of carbon atoms arranged in a flat honeycomb pattern whereby each hexagon is formed by six carbon atoms at its vertices. Since graphene's first isolation in 2004 -- which later led to a Nobel Prize in physics -- scientists and engineers have intensely studied its unique physical properties as well as its potential applications.
Dr. Fan Zhang, professor of physics in the School of Natural Sciences and Mathematics at UT Dallas, is a theorist who for more than a decade has been examining the electronic properties that emerge when layers of graphene are stacked in a chiral manner to form a rhombohedral structure.
