The increase in computer speed over the past few decades is notable, but it is coming to an end. One factor is that silicon itself has reached physical limits.
Recently, however, a new material, graphene, has been discovered that allows electrons to flow faster than silicon. Graphene consists of carbon atoms arranged in a single atom sheet. This is also a component of graphite forming a general pencil.
Graphene transistors can run electrons 100 to 1,000 times faster than today's silicon transistors.
The computer models developed in this research and the original simulation software are used to investigate the behavior of different graphene-based nanoelectronic devices such as FETs, detectors, and lasers.
