On-chip data communication and processing

In news

Scientists have developed electrically configured nanochannels that can eliminate unwanted energy waste and promise wave-based computing.

Significance
  • This can revolutionize on-chip data communication and processing in the future.       
Technology
  • Conventional electronics is composed of logic circuits having a large number of transistors interconnected by metallic wires.
  • The data carried by electric charges suffer undesirable heating limiting its integration density.
  • Spintronics, also known as spin electronics, or the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices offer to harness electron spins. 
  • Their collective precession can carry information encoded in its amplitude, phase, wavelength, and frequency without any physical motion of particles, eliminating unwanted energy waste and promising wave-based computing.
  • In the recent research, spin-waves were efficiently transferred through these nanochannels, and this could be switched ‘ON’ and ‘OFF’ and its magnitude altered by a meagre voltage of few volts.
