Research Bits: March 26

Skyrmion switches Researchers from the Agency for Science, Technology and Research (A*STAR) and National University of Singapore harnessed skyrmions to build a switch that has the potential to process data faster while using significantly less energy. Skyrmions are magnetic whirls that form in very thin metal layers and can be efficiently moved between magnetic regions. Using a magnetic tun... » read more

New Challenges Emerge With High-NA EUV

High numerical aperture EUV exposure systems are coming — as soon as 2025 by some estimates. Though certainly a less profound change than the introduction of extreme ultraviolet lithography, high-NA lithography still brings a new set of challenges for photoresists and related materials. With a higher numerical aperture, photons strike the wafer at a shallower angle. That requires thinner p... » read more

An achromatic X-ray lens

Abstract "Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date restricted their use to narrow-bandwidth radiation, essentially limiting such high-resolution X-ray microscopes to high-brightness synchrotron sources. Similar to visible light optics, one way t... » read more
