A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy’s Oak Ridge National Laboratory. While zinc sulfide nanoparticles – a type of quantum dot that is a semiconductor – have many potential applications, high […]
Paper Examines Clues for Superconductivity in an Iron-Based Material
For the first time, scientists have a clearer understanding of how to control the appearance of a superconducting phase in a material, adding crucial fundamental knowledge and perhaps setting the stage for advances in the field of superconductivity. The paper, published in Physical Review Letters, focuses on a calcium-iron-arsenide single crystal, which has structural, thermodynamic […]
