Light pulses control graphene's electrical behavior

Graphene, an ultrathin form of carbon with exceptional electrical, optical, and mechanical properties, has become a focus of research on a variety of potential uses. Now researchers have found a way to control how the material conducts electricity by using extremely short light pulses, which could enable its use as a broadband light detector. These findings could allow ultrafast switching of conduction, and possibly lead to new broadband light sensors.
