#Physicists see surprisingly strong light, high heat from nanogaps between plasmonic electrodes

Admin6 years ago08 mins

“#Physicists see surprisingly strong light, high heat from nanogaps between plasmonic electrodes” Rice University physicists discover that plasmonic metals can be prompted to produce “hot carriers” that in turn emit unexpectedly bright light in nanoscale gaps between electrodes. The phenomenon could be useful for photocatalysis, quantum optics and optoelectronics. Credit: Longji Cui and Yunxuan Zhu/Rice…
