BES Web Highlight: Single-mode gallium nitride nanowire lasers

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 […]
