Scientists build a nanolaser using a single atomic sheet

Scientists build a nanolaser using a single atomic sheet

University of Washington scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build and compatible with existing electronics. Lasers play essential roles in countless technologies, from medical therapies to metal cutters to electronic gadgets. But to meet modern needs in computation, communications, imaging […]

Plasmonic Nanoantennas: From Nanotweezers to Plasmonic Pho...

Kimani C. Toussaint Jr., Brian J. Roxworthy, Hao Chen, Abdul M. Bhuiya and Qing Ding Devices that convert optical radiation to spatially concentrated energy at the nanoscale are finding applications in data storage, spectroscopy, sensing and nanoscale optical manipulation. They can even serve as a plasmonic “film” for recording images or encoding sound. For those […]

Plasmonic nanostructures for enhanced LED efficiency

Plasmonic nanostructures for enhanced LED efficiency

“Shih-Hao Chuang and Dong-Sing Wuu” “A novel transparent electrode embedded with silver-based nanoparticles enhances the light extraction efficiency of LEDs, improving device performance by 88%.” Due to the important role that they play in solid-state illumination, LEDs represent a promising candidate for next-generation lighting technology. However, confinement—which occurs due to the large difference in refractive […]
