New Delhi: Researchers have come with a new version of `spaser` technology that can make mobile phones so flexible that they can actually be printed on your t-shirt.
Researchers at Monash University have modelled the world’s first spaser (surface plasmon amplification by stimulated emission of radiation) to be made completely of carbon.
As the name depicts, a spaser is actually a nanoscale laser or nano-laser where one of the lasers is replaced by sp.
It emits a beam of light through the vibration of free electrons, rather than the space-consuming electromagnetic wave emission process of a traditional laser.
Graphene and carbon nanotubes were chosen by the researchers to develop spaser as they can interact and transfer energy to each other through light.
It is to be noted that a spacer is a hundred times stronger than steel and can also withstand high temperatures.
Spaser-based devices can be used as an alternative to current transistor-based devices such as microprocessors, memory, and displays to overcome current miniaturising and bandwidth limitations.
The paper has been published in ACS Nano.
