A team of scientists at the University of Queensland (UQ) have shown off a semiconductor technology that they claim could revolutionise future computing.
Professor Jin Zou and Dr Yong Wang from UQ, collaborated with Intel and UCLA to make what they dub “magnetic quantum dots”.
The dots can use both “charge” and “spin” – outputs generated by electronics. And developing quantum dots able to use both outputs could well reduce the size of electrical devices and reduce power dissipation, said Zou.
“The collective spins in spintronics devices are expected to consume less energy than current charge based technology,” said Zou.
The team tested the technology at high temperatures. They believe that operating the technology under the right conditions will let it be integrated into existing silicon based microelectronic technology.
“This research will lead to greater efficiency and stability for electrical systems and information technology which provide essential infrastructure for every sector. We hope our work will help to improve the performance of microelectronics in applications used in health care to defence to communications,” said Dr Wang.
The Intel researcher involved was Dr Ajey Jacob, based in Santa Clara.
The research work was published in sci-journal Nature Materials.
