Gallium Nitride Nanowire Tips Function as LEDs

Probe tips for atomic force microscope can be used to illuminate tiny sample region with optical radiation. The National Institute of Standards and Technology (NIST), Gaithersburg, MD A team of researchers has demonstrated that atomic force microscope (AFM) probe tips made from its near-perfect gallium nitride nanowires are superior in many respects to standard silicon or platinum tips in measurements of critical importance to microchip fabrication, nanobiotechnology, and other endeavors. In addition, the scientists have invented a means of simultaneously using the nanowire tips as LEDs to illuminate a tiny sample region with optical radiation while it is scanning, adding an entirely new dimension to the characterization of nanoelectronics materials and devices.

New Technique Makes LEDs Brighter, More Resilient

Coating polar gallium nitride (GaN) with a layer of phosphorous-derived acid increases luminescence without increasing energy input. NC State University, Raleigh, NC Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium nitride (GaN) with a layer of phosphorus-derived acid.

Light-Emitting Properties of Quantum Dots Can Help Harvest Sunlight

Los Alamos National Laboratory A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca (UNIMIB), Italy. Their project demonstrates that the superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

NIST Studies Why Quantum Dots Suffer from ‘Fluorescence Intermittency’

The National Institute of Standards and Technology (NIST) Researchers at the National Institute of Standards and Technology (NIST), working in collaboration with the Naval Research Laboratory, have found that a particular species of quantum dots that weren't commonly thought to blink, do. Although the blinks are short — on the order of nanoseconds to milliseconds — even brief fluctuations can result in efficiency losses that could cause trouble for using quantum dots to generate photons that move information around inside a quantum computer or between nodes of a future high-security internet based on quantum telecommunications.
