Magnetic memory device is smallest demonstrated and uses record-low current. Memory-hungry, power-sapping big data might finally have met its match.

Electrical engineers at Northwestern University and the University of Messina in Italy have developed a new magnetic memory device that could potentially support the surge of data-centric computing, which requires ever-increasing power, storage and speed.

Based on antiferromagnetic (AFM) materials, the device is the smallest of its kind ever demonstrated and operates with record-low electrical current to write data.

“The rise of big data has enabled the emergence of artificial intelligence (AI)...

Protected surface states are akin to corner states of higher-order topological insulators. An international team of scientists has discovered an exotic new form of topological state in a large class of 3D semi-metallic crystals called Dirac semimetals...

A nanoscale gold butterfly provides a more precise route for growing/synthesizing nanosized semiconductors that can be used in nano-lasers and other applications.

Hokkaido University researchers have devised a unique approach for making nanosized semiconductors on a metal surface. The details of the method were reported in the journal Nano Letters and could further research into the fabrication of nanosized light and energy emitters.

The approach, developed by Hokkaido University’s Research Institute for Electronic Science and Hokkai-Gakuen University, involves generating localized heat on a gold nanoparticle within a ...

Researchers develop a new platform for all-optical computing. The future of computation is bright – literally.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with researchers at McMaster University and University of Pittsburgh, have developed a new platform for all-optical computing, meaning computations done solely with beams of light.

“Most computation right now uses hard materials such as metal wires, semiconductors and photodiodes to couple electronics to light,” said Amos Meeks, a graduate student at SEAS and co-first author of the research...
