UCLA chemists, engineers achieve world record with high-speed graphene transistors
Date:9/4/2010

roup was able to overcome alignment difficulties previously encountered and fabricate very short-channel devices with unprecedented performance."

These advances allowed the team to demonstrate the highest speed graphene transistors to date, with a cutoff frequency up to 300 GHz comparable to the very best transistors from high-electron mobility materials such gallium arsenide or indium phosphide.

"We are very excited about our approach and the results, and we are currently taking additional efforts to scale up the approach and further boost the speed." said Lei Liao, a postdoctoral fellow at UCLA.

High-speed radio-frequency electronics may also find wide applications in microwave communication, imaging and radar technologies.
