Understanding the interaction between light and matter at the smallest scales (angstrom scale) is essential for advancing technology and materials science. Atomic-scale structures, such as defects in ...

Scientists have achieved one-nanometer optical resolution in a microscope that can visualize how light interacts with individual atoms and molecules. The technique, called ultralow tip oscillation ...

Scientists at the Department of Energy's Oak Ridge National Laboratory have reimagined the capabilities of atomic force microscopy, or AFM, transforming it from a tool for imaging nanoscale features ...
