Graphene is used to create the world’s smallest light bulb by researchers. Graphene is a layer of pure carbon just one atom thick which is 200 picometers: one picometer is one trillionth of a meter. Stronger than steel, it is transparent, light and flexible and possesses uncommon electric and thermal properties.
In the latest research, published in the journal Nature Nanotechnology, scientist show that graphen can be manipulated to produce a bright light as well.
The ultrathin graphene was turned into a superheated filament just like the thin wire of an incandescent light bulb – which glowed at a temperature of about 2500C.
It could be integrated as a light source into chips or thin, flexible and transparent displays, it can be used in smartphones, computers, buildings and satellites.
“We can turn the light in graphene on and off very fast—which means we can send information very fast,” said Dr. Kim.
