ECIS-Veeco: Research Driving Down the Costs of Efficient LED Lighting

Solid state lighting (SSL), which uses light-emitting diodes (LEDs), has the potential to be 10 times more energy efficient than traditional incandescent light bulbs. Currently, 20% of U.S. energy use powers lighting. SSL technology can potentially significantly cut U.S. lighting energy use, reducing electricity consumption for lighting by one-fourth. That’s why since 2003, the Department [...]

Sandia and General Motors: Advancing Clean Combustion Engines with Predictive Simulation Tools

On February 14, 2013, in CRF, Energy, Partnership, Transportation Energy

Sandia National Laboratories has been working with General Motors (GM) for over 30 years. In the last few years, this partnership has become a strategic alliance, which includes a cooperative research and development agreement (CRADA), making it easier for the partners to work together. Our parthership’s research focus areas include systems modeling for energy, infrastructure, [...]

BES Web Highlight: Single-mode gallium nitride nanowire lasers

On January 28, 2013, in EC, Energy Efficiency, Solid-State Lighting

A new top-down method for fabricating gallium nitride (GaN) nanowires with precisely controlled geometries enables single-mode, rather than typically-observed multi-mode, lasing behavior. Single-mode lasing arises from strong mode competition induced by careful restriction of the nanowire dimensions. This research was published by Sandia National Laboratories and is featured in a BES EFRC newsletter that highlights the [...]

“Solid-state Lighting: ‘The case’ 10 Years After and Future Prospects” paper will be translated in Chinese

In 2011, ERFC scientist Jeff Tsao, in conjunction with Roland Haitz and Taiming Zhou, published an SSLS paper titled, “Solid-state Lighting: ‘The Case’ 10 Years After and Future Prospects”. The paper critiques a previously released white paper titled, “The Case for a National Research Program on Semiconductor Lighting” while providing new predictions for the next [...]

NASA Earth at Night Video

Have you ever wondered what the Earth looks like at night? NASA provides a clear, cloud-free view of the Earth at night using the Suomi National Polar-orbiting Partnership Satellite. The satellite utilizes an instrument known as the Visible Infrared Radiometer Suite (VIIRS), which allows the satellite to capture images of a “remarkably detailed view of [...]
