2013 SPIE Intweviews George Wang: Developing next-generation lighting using nanowires January 14, 2013 George Wang, a senior investigator in the SSLS, was interviewed about his work in the EFRC on nanowire growth and the possibility of achieving ultra-efficient solid-state lighting. You may view his interview at: http://spie.org/x91938.xml 2012 Red-Emitting Quantum Dotes for Solid-State Lighting December 3, 2012 [...]
June 22, 2011 In a paper titled “Nanoscale Effects on Heterojunction Electron Gases in GaN/AlGaN Core/Shell Nanowires” published in Nano Letters, Sandia scientist Bryan M. Wong, and EFRC scientists François Léonard, Qiming Li, and George T. Wang, present a theoretical and computational study of the electronic properties of core/shell nanowires. They find that the nanometer size [...]
June 27-28, 2011 The rebound (or take-back) effect) is the term in energy economics used to describe the effectin which increases in energy efficiency do not necessarily lead to simple 1:1 decreases in energy consumption, but instead are “taken back” in the form of higher consumption of the goods and services that the energy is [...]
July 4, 2011 Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors. Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors. Therefore it is a common belief [...]
