Singapore researchers have successfully designed and fabricated electrical circuits that can operate at hundreds of terahertz frequencies, which is tens of thousands times faster than today’s state-of-the-art microprocessors.
This novel invention uses a new physical process called ‘quantum plasmonic tunnelling’. By changing the molecules in the molecular electronic device, the frequency of the circuits can be altered in hundreds of terahertz regime. The new circuits can potentially be used to construct ultra-fast computers or single molecule detectors in the future, and open up new possibilities in nano-electronic devices.
