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 [...]

Sandian Served as President of the National Institute of Ceramic Engineers

During FY12, (Electrical, Optical, & Nano Materials Department in Materials Science & Engineering) served as the President of the National Institute of Ceramic Engi­neers, a Class of the American Ceramic Society (ACerS) that represents the ceramic materials community for accreditation† and licensure‡ activities. During the same period, Geoff also served in a related but expanded [...]

Sandia Demonstrated First-Time, Single-Mode Lasing in Gallium-Nitride Nanowire Lasers

Semiconductor nanowire lasers have attracted intense interest as promising compact, low-power coherent light sources for on-chip applications, many of which (e.g., imaging, multiplex communica­tion, data storage) desire high beam quality and spectral purity—conditions that can be satisfied by single-mode operation in nanowire lasers. However, due to the lack of mode-selection mechanisms, most reported nanowire lasers exhibit [...]

Sandia Wide-Bandgap Semiconductor Workshop

In response to increased interest in wide-bandgap (WBG) semiconductor projects by DOE, on October 30, 2012, Sandia hosted a one-day brain­storming workshop aimed at identifying the value, scope, structure, and partnership oppor­tunities of a potential National Center for Wide Bandgap Semiconduc­tors. Participants from DOE, industry, academia, and other labs participated in a series of breakout [...]

American Chemical Society International-Domestic Student Summit

Undergraduate Ms. Kathleen Martin and graduate student Ms. Aruny Loch from our local New Mexico section of the American Chemical Society (ACS) have been invited to attend the ACS International-Domestic Student Summit in Raleigh, North Carolina, preceding the ACS Southeastern Regional Meeting. The team is from the University of New Mexico (UNM)—student researchers at at [...]
