A Nanomaterial To Make Flexible Electronic Devices & Solar cells
South Korean scientists on Thursday unveiled a manufacturing process for large-scale, nanomaterial films that can herald the production of flexible electronic devices.The Sungkyunkwan University-Samsung Advanced Institute of Technology (SAIT) team, said graphene film with a diameter of 10 cm has been created by adopting a conventional chemical vapor deposition (CVD) technique.
Graphene is a one-atom-thick, honeycomb-like nano material structure that can handle 100 times more electric current than copper and transfer electrons 100 times faster than monocrystalline silicon, used in conventional semiconductors.
The wafer-scale graphene is expected to be used in flexible displays, wearable computers and advanced transistors and electrodes. It can also replace indium tin oxide, used extensively in the production of touch-screen panels and solar cells. The CVD technique calls for heating a mixture of methane, hydrogen and argon gases to 1,000 C and using it to attach carbon atoms to a 300 nanometer-thick, flat nickel catalyst
