Researchers have created the world’s thinnest light bulb using graphene (an atomically thin and perfectly crystalline form of carbon) instead of tungsten as a filament.
- Led by Young Duck Kim, a postdoctoral research scientist in James Hone’s group at Columbia University School of Engineering, a team of scientists from Columbia, Seoul National University, and Korea Research Institute of Standards and Science have made it possible.
About the Bulb:
- The bulb uses Graphene as a filament. When an electric current runs through the filament, it heats up enough to emit light.
- This graphene light is low cost with a relatively simple structure.
- The visible light from atomically thin graphene is so intense that it is visible even to the naked eye, without any additional magnification.
- It can be used as ‘broadband’ light emitter and can be integrated into chips. This will pave the way towards the realisation of atomically thin, flexible and transparent displays and graphene-based on chip optical communications.
Graphene is an allotrope of carbon and is famous for being stronger than steel and more conductive than copper.
