Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

Scientists from the Massachusetts Institute of Technology (MIT) in the U.S. have made a groundbreaking achievement after they captured the first images of individual atoms freely interacting in space.

have found a new way to image layers of boron nitride that are only a single atom thick. This material is usually nearly invisible in optical microscopes because it has no optical resonances. To ...

Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic ...

Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type ...

In a quiet lab at Argonne National Laboratory, Saw-Wai Hla and his team were huddled around their instruments late one night when they detected the spectral signature they had been searching for. The ...
