Graphene shown to be the fastest semiconductor

Abstract:
The University of Manchester has proved graphene is the fastest semiconductor.

"We knew this material is exceptionally good, but we couldn't put a number on it," Professor Andre Geim, director of the University's Centre for Mesoscience and Nanotechnology told Electronics Weekly.

His team has proved mobility is above 200,000cm2/Vs at room temperature. "Greater than 100 times that of silicon, 30 times GaAs, and larger even than carbon nanotubes," he said. "It is the only material where electrons at room temperature can move thousands of interatomic distances without scattering."
