New version of spaser technology (amplification of surface plasmons through stimulated radiation) can make mobile phones are so compact, efficient, and flexible that their can be printed on clothes.
A team of researchers from Monash University has managed model the world’s first spaser, consisting entirely of carbon.
A spaser is actually a nanolaser. It emits a ray of light through oscillations of free electrons, instead of enough cumbersome process of emission of electromagnetic waves traditional laser. The carbon structure of the new spaser gives it a lot advantages.
Use of carbon (as opposed to gold or silver nanoparticles and semiconductor quantum dots of traditional spazers) makes the new device more durable and flexible and allows him to work at high temperatures.
Spaser-based devices can be used as alternatives to modern transistor systems – for example, in microprocessors, memory and monitors.
Researchers from the University use material for their spaser. Nun chose graphene and carbon nanotubes. They are more than a hundred times stronger than steel and can conduct heat and electricity much better than copper. Their studies first showed that graphene and carbon nanotubes can interact and transfer each other energy through light. These optical interactions extremely fast and energy efficient – and therefore are well suited for various applications, for example – in computer chips.
