Graphene
March 24, 2008 at 12:23 PM
University of Maryland physicists (CNAM) have shown that in graphene the intrinsic limit to the mobility, a measure of how well a material conducts electricity, is higher than any other known material at room temperature (100 times faster than in silicon!). Graphene is an atomic-scale chicken wire made of carbon atoms. It’s a very promising material which combines aspects of semiconductors and metals, extremely useful for applications in which transistors much switch extremely fast, such as in processing extremely high frequency signals.
Research results were published online in the journal Nature Nanotechnology.
