Like small-scale Legos clicking into place, nature autonomously puts together microscopic building blocks. Living systems are biochemical machines that excel at building and moving their parts. Just as machines need energy in some form to operate, living systems are energized by consuming “fuel”—substances…
Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently “tunneling” electrons through a tiny barrier. The work brings plasmonics research a step closer to realizing ultra-compact…
