Graphene Lights The Way
Everyone knows that graphene is slowly rising to the occasion of the “super” semiconductor that many believe it today. In the latest discovery, scientists were able to create the world’s thinnest light-bulb by using strips of 1-atom thick carbon as the filament. Not only did they produce this incredible light-source, but they did it as an on-chip component, meaning that these developments may play an important role in the area of optical computing (aka integrated photonic circuits).
With the ability to adjust the intensity of the light by increasing or decreasing the distance of the silicon substrate beneath the filament they are able to easily tune into the ideal frequency of light “vibration”. The key advantage of graphene in the construction of light-emitting components is that it actually becomes less conductive as it’s temperature increases. This means that where most other filaments would end up causing collateral damage due to inability to withstand high temperatures, graphene is able to not only withstand the temperatures but it actively becomes resistant to the spreading of those temperatures as more power is applied. Cool stuff!
