Answer: (c)
Related Facts:-
- Scientists have developed electrically configured nanochannels that can eliminate unwanted energy waste and promise wave-based computing.
- Research regarding such nanochannels has been done by Professor Anjan Barman and co-workers from the S. N. Bose National Centre for Basic Sciences.
- S. N. Bose National Centre for Basic Sciences is an autonomous institute under the Department of Science and Technology (DST), Government of India.
- This can revolutionize on-chip data communication and processing in future.
- Conventional electronics is composed of logic circuits having a large number of transistors interconnected by metallic wires.
- Basis of electrically configured nanochannels is Spintronics, which is also known as spin electronics, or the study of the intrinsic spin of the electron and its associated magnetic moment.
- Spintronics is now newly developed method through which information can be carried in the form of amplitude, phase, wavelength, and frequency without any physical motion of particles
- We all know that data carried by electric charges suffer undesirable heating limiting its integration density.
- Spintronics, in addition to its fundamental electronic charge, in solid-state devices offer to harness electron spins.
- It helps in eliminating unwanted energy waste and promising wave-based computing.
- Professor Anjan Barman and his team have done this by periodically tailoring the property that confers a preferred direction on the spin of a system.
- This technique is also called anisotropy using the electric field technically called the principles of voltage-controlled magnetic anisotropy.
- This work has been published in the journal Science Advances.
- In the recent research, spin-waves were efficiently transferred through these nanochannels.
- This could also be switched ON and OFF and its magnitude altered by a meagre voltage of few volts.
- The team believes that in future, these nanochannels can be engineered further to transfer specific bands of frequencies through designed parallel channels towards development of on-chip multiplexing devices.
