Nanoscale Effects on Heterojunction Electron Gases in GaN/AlGaN Core/Shell Nanowires

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 […]

Jeff Tsao participates in “Energy Efficiency and the Rebound Effect” Workshop

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 […]

Four-color laser white illuminant demonstrating high color-rendering quality

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 […]
