Intel is working with scientists at the University of California at Berkeley to expand beyond existing transistor technology to pave the way for a new type of computer memory and logic circuits using advanced quantum materials..
A study was published yesterday describing a method for converting relatively new types of materials (multiferroics and topological materials) into computing and storage devices that will consume 10-100 times less energy, and will increase the efficiency of microprocessors. Magnetoelectric spin-orbit (MESO) devices will be able to perform five times more logical operations per unit of space than existing semiconductors.
In MESO devices, binary bits are magnetic spin states moving from top to bottom in a multiferroic. Scientists claim that they have reduced the voltage required to switch between 0 and 1 to 500 millivolts, and then 100 mV can be achieved. This will reduce the power consumption of future transistors by about 30 times..
In the picture: atoms of bismuth (blue), oxygen (yellow), iron (gray).
Multiferroics – these are materials whose atoms have more than one «collective state». MESOs are based on one such material with unique quantum properties, bismuth, iron and oxygen (BiFeO3), which is both magnetic and ferroelectric. These two characteristics are related and interdependent. By controlling the electric field, you can change the magnetic state.
New devices will drive technologies that require significant processing power with low power consumption. For example, unmanned vehicles and flying vehicles, IoT devices, artificial intelligence systems.
Researchers predict that the rapid development of the computer chip industry will increase the share of their power consumption from 3% to 20%. Therefore, they are looking for revolutionary rather than evolutionary solutions to the issue, and believe that MESO will eventually replace the ubiquitous semiconductor transistors..
PC & SBC Power Consumption
In parallel with bit computers, quantum computers are also developing. The first single-photon transistor was recently developed that can process 10 billion cubits per second and is a million times smaller than a grain of salt..
