Graphene: A Super-Speed Semiconductor?

By March 25, 2008

Follow me on:

About a year ago, we reported on a graphene nano-transistor. A new study from the University of Maryland indicates that electrons in graphene move at a rate over 100 times faster than in silicon, which has strong implications for advanced semiconductors.

This rating is determined by measuring the "mobility" of the electrons, which indicates the speed at which a device, such as a transistor, can turn on and off. The research helps support a growing notion that we may in the future transition from silicon-based electronics and computer technology to a graphene-based technology, at least for sophisticated and delicate technologies such as high frequency receivers.

Now could this technology be used to increase the overall efficiency of solar cells as well?
Also, graphite the only element in which this is possible?
