For the past 25 years, scientists and engineers from the Center for X-Ray Optics (CXRO) have worked to develop EUV lithography, a technique that enables microchip circuits and transistors that are tens of thousands of times thinner than a strand of human hair. Patrick Naulleau, a CXRO scientist who helped develop EUV lithography, shares his perspective in this Q&A. Read more »

Exploring Critical Synthetic Parameters for Nanoscale ε-Fe2O3 and Their Influence on Magnetic Behaviors
An intermediate polymorph of iron oxide, ε-Fe2O3, has attracted significant attention for potential applications in high-frequency mm-wave absorption and high-density magnetic recording. However, fabrication is still a challenge. Here, we identified critical reaction parameters to improve the phase purity and tested their effects. Read more »
Infrared Probe of Ultrahigh-Quality Nanoribbon Resonators
Researchers found that ribbon-like thin films, grown through a bottom-up, self-assembly approach, can act as ultrahigh-quality nanoscale resonators of lattice vibrations at infrared frequencies. These ultrathin nanostructures are ideal platforms for applications that harness infrared light, such as thermal emission and molecular sensing. Read more »
