The “zeroth” scientific research challenge is what we call overarching and spillover research. “Overarching” research is what connects the six main scientific research challenges to SSL technology. SSL technology is itself evolving rapidly, and we devote some effort to understanding this evolution so as to provide guidance for the directions of our inquiry to surmount [...]
EFRC scientist, Weng Chow, recipient of the 2013 Quantum Electronics Award. EFRC Sr. Investigator Weng Chow is the recipient of the 2013 Quantum Electronics Award. This highly prestigious award presented by the IEEE Photonics Society is given to a select group of scientists who are considered pioneers in the field of quantum electronics. [...]
EFRC scientist Jeff Tsao, in conjunction with Sandian Erik Spoerke and UNM scientist Patrick Johnson, volunteered at Explora Museum over the weekend. The three scientists participated in a program event hosted by Explora called Portal to the Public, whose goal is to, "Engage in experiential activities with scientists that are your neighbors in the c0mmunity." [...]
One of our SSLS scientists, Jonathan Wierer, is presenting at the Illuminating Engineering Society (IES)-Albuquerque section meeting. The goal of IES is to, “improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that will benefit the general populace.” His talk titled, “Latest SSL work at Sandia [...]
SSLS scientist George Wang presented at tSSL on March 26th-27th. George Wang, a senior investigator in solid-state lighting science, was invited to speak at the 7th Taiwan Solid-State Lighting (2013 tSSL). The conference was held on March 26th-27th in Taipei, Taiwan. The purpose of tSSL is "to bring together scientists and engineers actively [...]
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 [...]
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 [...]
Professor Emmanouil (Manos) Kioupakis, from the University of Michigan, visited Sandia for technical discussions and to give a seminar on "Auger Recombination in Nitride Light-Emitting Diodes from First Principles Calculations." Professor Kioupakis just finished a post-doc with Professor Chris van de Walle at UC Santa Barbara, and has been doing first-principles calculations of Auger recombination [...]
