For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively ...
(Phys.org)—For the first time, researchers have synthesized semiconducting gallium telluride (GaTe) in the monoclinic phase as a pseudo-one-dimensional (pseudo-1D) material. This new class of materials is characterized ...
When scientists remove individual atoms in a semiconductor material, the resulting vacancies become point defects. Contrary to what their name implies, these defects can have beneficial effects on the semiconductor's properties ...
(Phys.org) —The mention of a two-dimensional material with excellent electrical and optical properties may first bring to mind graphene. However, this description also fits another class of materials called transition metal ...
As a result of achieving high imaging dynamic range, a team of astronomers in Japan has discovered for the first time a faint radio emission covering a giant galaxy with an energetic black hole at its center. The radio emission ...

Astronomers have reported the discovery of a new galactic supernova remnant (SNR) in the Cepheus constellation. The newly detected SNR is relatively large and optically bright, but faint in radio and X-ray bands. The finding ...
Researchers drew attention three years ago when they reported that a two-dimensional perovskite—a material with a specific crystal structure—composed of cesium, lead and bromine emitted a strong green light. Crystals ...
