Researchers from Monash University use graphene and carbon nanotubes to develop a spaser (a nano-laser that emits a beam of light through the vibration of free electrons unlike the electromagnetic wave-emission process of regular lasers).
This new spaser is more robust and flexible compared to regular spasers made from silver and quantum-dots. It can also withstand high temperatures and is eco-friendly.
Possible applications for such spasers include cancer treatment (destroying cancer cells). The researchers also say that spaser-based devices may one day be used as an alternative for transistors used in CPUs, memory devices and displays.
