World’s ‘Thinnest’ Light Bulb, Made From Graphene, Debuts
Discovery could eventually transform computers as well.
The quest for the better light bulb has taken yet another leap. This time, nanotechnology derives light from atom-thin strips of one of the world’s strongest materials: graphene.
For the first time, scientists say they’ve created a flexible and transparent light source with carbon in its purest form. They say their discovery could also eventually transform computers by using light rather than electronic circuits in semiconductor chips.
“We’ve created what is essentially the world’s thinnest light bulb,” says Columbia University engineering professor James Hone in announcing the findings. He co-authored a study, published Monday on Nature Nanotechnology's website, by a team of researchers from South Korea, Columbia's Fu Foundation School of Engineering and Applied Science, Stanford University and University of Illinois at Urbana-Champaign.
