New nanomaterial to replace mercury
June 6, 2019

NTNU researchers from the Department of Electronic Systems have succeeded in creating ultraviolet light on a graphene surface. This development could result in nontoxic LEDs becoming a commonplace equipment in people’s homes in a few years.
 
The NTNU research team have collaborated with Professor Katsumi Kishino at Sophia University in Tokyo, where they have used an MBE machine to grow aluminium and gallium atoms directly on the graphene substrate. After this, the samples have been transported to NTNU NanoLab where the researchers have made metal contacts of gold and nickel on the graphene and nanowires. When power is sent from the graphene and through the nanowires, they emit UV light.
