The discovery of asymmetric diffraction in acoustic waves opens new avenues for innovative communication devices, impacting ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication ...

Researchers have built a deep-ultraviolet microscope to study hard-to-analyze materials like diamond, offering a new way to probe their electronic and thermal properties at the nanoscale. This ...

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap ...

However, using an atom-thick layer of carbon atoms known as graphene, experts found that even after 100 hours under irradiation of an atom beam, the grating showed no damage and diffraction still ...

Atom diffraction had so far been seen in reflection. The atoms were bounced off a surface that was etched to have a grating. The lines don’t need to be as thin as 10,000 times smaller than a ...

The story begins several decades ago, in 1927, when physicist George Paget Thomson revealed that electrons, when passed through a crystal grating, produce a diffraction pattern—a hallmark of ...
