Claiming that something has a defect normally suggests an undesirable feature. That s not the case in solid-state systems, such as the semiconductors at the heart of modern classical electronic devices. They work because of defects introduced into the rigidly ordered arrangement of atoms in crystalline materials like silicon. Surprisingly, in the quantum world, defects also play an important role. Researchers at the U.S. Department of Energy s (DOE) Argonne National Laboratory, the University of Chicago and scientific institutes and universities in Japan, Korea and Hungary have established guidelines that will be an invaluable resource for the discovery of new defect-based quantum systems. The international team publi ....

E-Mail IMAGE: Artist s conception of polar vortices moving in ferroelectric material. These small groupings of atoms must be excited with high-frequency electric fields to move, but studying their behavior may lead to. view more Credit: Ellen Weiss/Argonne National Laboratory Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity. In 2016, the study of ferroelectrics got more interesting with the discovery of polar vortices essentially spiral-shaped groupings of atoms within the structure of the material. Now a team of researchers led by the U.S. Department of Energy s (DOE) Argonne National Laboratory has uncovered new insights into the behavior of these ....
Nanotechnology Now Home > Press > Better solutions for making hydrogen may lie just at the surface The unique interactions between perovskite oxide, its changing surface layer, and iron species that are active toward the OER paves a new path for the design of active and stable materials, bringing us one step closer to efficient and affordable green hydrogen production. CREDIT Argonne National Laboratory Abstract: A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That s because, even though hydrogen is abundant, it must be derived from another substance that contains it and today, that substance is often methane gas. Scientists are seeking ways to isolate this energy-carrying element without using fossil fuels. That would pave the way for hydrogen-fueled cars, for example, that emit only water and warm air at the tailpipe. ....
