Study published Wednesday in Characteristics Scientific Reports lays away a theoretical map to work with ferroelectric materials to process information using multivalued logic - a leap beyond the simple ones and zeroes that make up our current computing systems that could let us process information much more efficiently.

The Chinese language of computers is written in just two icons - ones and zeroes, meaning yes or no. But a global of wealthier possibilities awaits us if we could expand to three or more ideals, in order that the same physical change could encode much more information.

Most importantly, this novel logic unit will permit information processing using not only "yes" and "no", but also "either yes or no" or "maybe" operations, " said Valerii Vinokur, a materials scientist and Distinguished Many other at the U. S i9000. Department of Energy's Argonne National Laboratory and the corresponding author on the paper, along with Laurent Baudry with the Lille University of Science and Technology and Igor Lukyanchuk with the University of Picardie Jules Verne.

This kind of is the way our brains operate, and they're something on the order of several times more efficient than the best computers we've ever handled to build - while consuming orders of size less energy.

Our minds process so much more information, when our communication were built like our current computers are, the brain would not merely skin boil but evaporate from the energy they use, inch Vinokur said.

While the features of this kind of work, called multivalued logic, have long been known, the condition is that we haven't uncovered a material system that could implement it. Most suitable now, transistors can easily operate as "on" or "off, " so this new system would have to find a different way to constantly maintain more states - as well as be easy to read and write and, ideally, to work at room temperature.

Hence Vinokur and the team's interest in ferroelectrics, a school of materials whose polarization can be handled with electric fields. As ferroelectrics physically change condition when the polarization changes, they're very helpful in sensors and other devices, such as medical ultrasound machines. Researchers are incredibly enthusiastic about tapping these properties for computer memory space and other applications; but the theory behind their behavior is greatly still emerging.

This is the way our brains operate, and they're something on the order of a million times more effective than the best computers we have ever managed to build - while consuming instructions of magnitude less energy.

The new paper lies out a recipe by which we're able to tap the properties of very thin films of any particular class of ferroelectric material called perovskites.

Based on the calculations, perovskite films could hold two, three, or even four polarization positions that are energetically steady - "so they could 'click' into place, and so provide a stable system for encoding information, inches Vinokur said.

The team calculated these stable constructions and how to change the polarization to move it between stable positions using electric fields, Vinokur said.

When we realize this in a device, it will enormously raise the efficiency of memory products and processors, " Vinokur said. This offers a significant step towards conclusion of so-called neuromorphic computer, which strives to model the human brain inch.

Vinokur said the team is dealing with experimentalists to apply the principles to make a working system.
