Computers today have become more compact and faster than their predecessors. Likewise the latest models of transistors are likely to have major structural changes with dimensions not more than 10 nanometers. If computers get faster and more energy-efficient, they would require to process data using light particles in place of electrons. This is what is known as “optical computing.”

Fiber-optic networks are already transporting data via light over long distances. Also they are successful in achieving the same at a high speed with lesser loss. To research on possibilities of saving energy, researchers from various parts of the world have come together. In one of the latest studies, researchers have been evaluating silver’s potential in helping save energy.

Team of Researchers Led by Professor Tim Liedl

Tim Liedl, PI at Nanosystems Initiative Munich (NIM), besides which he is also a Professor of Physics at Ludwig-Maximilians-Universitaet (LMU) has published an article in the Nature Physics journal in collaboration with his colleagues from the Ohio University. The article describes how silver nanoparticles can be used to reduce energy consumption. The physicists to showcase their findings built a prototypical miniature test track. It was approximately 100 nanometers in length and was composed of three nanoparticles: A silver nanoparticle was placed in the middle, with one gold nanoparticle at either end.

The silver therefore served as an intermediary between the gold particles, however, it did not dissipate energy. To oscillate the silver particle’s plasmon, more energy is needed than what is required for old. Therefore, energy actually flows about the silver particle. Tim Liedl later explained that transport is facilitated by linking the electromagnetic fields surrounding the hot-sports, created between the silver particle and the two gold particles on the either side. This allowed energy to be transported with minimal or almost no loss and in a femtosecond time-scale.

Researches such as these, when assume real shape and get deployed across the world, they could resolve concerns pertaining to energy saving from its core.
