Aug 29, 2024 (Nanowerk News) Miniaturization is one of the fundamental qualities of modern electronics and is largely responsible for the incredible increments in performance witnessed over the past decades. To keep this momentum going, it is necessary to achieve circuit patterns finer than the existing ones on semiconductor chips,...
Tiny new lasers fill a long-standing gap in the rainbow of visible-light colors
Aug 29, 2024 (Nanowerk News) It’s not easy making green. For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ — injecting electric current into semiconductors — hasn’t worked as well in building tiny lasers that emit light at yellow...
Novel metamaterial design transforms stealth, telecommunications, and medical imaging
Aug 29, 2024 (Nanowerk Spotlight) Radar technology has reached a point where it can detect the faintest electromagnetic signals, challenging even the most advanced stealth technologies. The evolution of radar systems has outpaced traditional methods of evasion, such as specialized coatings and structural modifications, which are no longer sufficient against...
