Recently, an international team composed of researchers from Columbia University in the United States, Seoul National University and the Korea Institute of Standard Science finally found that graphene filaments can help develop graphene chip optical communication technology through various experiments, which is a major breakthrough in science and technology!
For the first time, scientists have demonstrated a visible light source using graphene only one carbon atom thick as a filament: a thin strip of graphene filaments connected to metal electrodes and suspended above the substrate, where the filament glows
with heat when an electric current passes.
The study was published in Nature Nanotechnology
.
Fengren Wang, a co-author of the study and a professor in Columbia University's Department of Mechanical Engineering, said the new "broadband" emitters can be integrated into chips, which is expected to pave the way
for flexible, transparent displays with only atomic thicknesses and optical communications based on graphene chips.
By measuring the spectrum of light emitted by graphene, the researchers found that graphene reached temperatures above 2500 degrees Celsius, enough to shine
brightly.
The visible light emitted by atom-thick graphene is so intense that it can be seen
with the naked eye without additional magnification.
Graphene reaches such high temperatures without melting substrates or metal electrodes because it has an interesting property: when heated, graphene becomes a poor conductor of heat
.
This means that the high temperature is confined to
a small "hot spot" in the center.
