Nanogaps Between Metals Create Light Ten Thousand Times Brighter Than Expected
Nanogaps between plasmonic electrodes produced 10,000 times more light than expected. Hot electrons were created by electrons driven to tunnel between gold electrodes, their recombination with holes emitted bright light, and the greater the input voltage, the brighter the light. This could be useful for applications in optoelectronics, quantum optics and photocatalysis. The effect depends …
