As the growth in global electricity need and supply continues to accelerate, efficient power electronics will be key to ...

Making devices that are defect-free and able to withstand years of harsh environments is made more difficult by a combination ...

and tantalum oxide (Ta 2 O 5) through ion-beam-assisted deposition (IBD) to form a bottom-distributed Bragg reflector, followed by a SiO 2 defect layer. A 9-nm niobium-titanium nitride (NbTiN ...

Silicon nitride ceramics are considered to be an ideal matrix for preparing metamaterials due to their high insulation, high thermal conductivity, high temperature resistance, corrosion resistance ...

Quantum Tornadoes in Momentum Space Mar. 10, 2025 — Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum ...

In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like ... To study the interactions between electrons in a material, physicists have come up with a number of ...

However, aside from new gold alloys, it has been relatively quiet on the metals front. Using tantalum isn’t new, but it’s so uncommon that it deserves attention whenever a watch brand chooses it. When ...
