Scientists create new type of semiconductor that holds superconducting promise

Scientists have long sought to make semiconductors—vital components in computer chips and solar cells—that are also superconducting, thereby enhancing their speed and energy efficiency and enabling new quantum technologies. However, achieving superconductivity in semiconductor materials such as silicon and germanium has proved challenging due to difficulty in maintaining an optimal atomic structure with the desired […]

Discovery of a new principle: Chiral molecules adhere to magnets

A research group at The University of Tokyo has discovered a new principle by which helical chiral molecules acquire spin through molecular vibrations, enabling them to adhere to magnets. Until now, it was believed that chiral molecules could only exhibit magnetic properties when an electric current was applied. This discovery overturns that conventional understanding.

Machine learning enables real-time analysis of iron oxide thin film growth in reactive magnetron sputtering

Researchers at University of Tsukuba have developed a technology for real-time estimation of the valence state and growth rate of iron oxide thin films during their formation. This novel technology was realized by analyzing the full-wavelength data of plasma emission spectra generated during reactive sputtering using machine learning. It is expected to enable high-precision control […]

Mirrorless laser: Physicists propose a new light source

A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical Review Letters, shows that quantum emitters spaced at subwavelength distances can constructively synchronize their photon emission to produce a bright, very narrow-band light beam, […]

Electric signals reveal magnetic spin waves, hinting at faster computing

Today’s computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to run programs and process information, computers rely on electricity. Each calculation requires a transfer of information between the electric and magnetic systems. This back-and-forth is a major bottleneck in the speed of modern computing.

Topological insulator maintains quantum spin Hall effect at higher temperatures

Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely limited to date. Researchers at the University of Würzburg have now developed a topological insulator that also works at higher temperatures. Their results are published in Science Advances.
