Using Carbon to Control the Light

The flip of a light switch — a nano-scale light switch — may some day dramatically boost the speed of data transmission, from streaming movies to accelerating the most data-intense computation. Today, information flow in a computer is based on electrical pulses. But if an electrical signal could instead control a light switch, the “ones and zeros” that give data meaning could race through computer circuits at ten times the current speed. A ten-fold increase in speed would mean a similar spike in the volume of information that can be processed. Research on this nano-scale light switch is being conducted by Berkeley Lab materials scientist Feng Wang, as part of his UC Berkeley Bakar Fellowship. More>
