Several Energy Frontier Research Centers Investigate Solid State Lighting
LIGHTimes News StaffAugust 11, 2009...U.S. Energy Secretary Steven Chu announced the delivery of $377 million in funding for 46 new multi-million-dollar Energy Frontier Research Centers (EFRCs) located at universities, national laboratories, nonprofit organizations and private firms across the nation. Some $277 million of the $377 million comes from funding made available through the Recovery Act, with the remaining $100 million made from DOE's FY2009 budget. The 46 EFRCs are to be funded at $2 to $5 million per year each for a planned initial five-year period. In total, the EFRC initiative represents a planned DOE commitment of $777 million over five years. The EFRCs were reportedly selected from a pool of applications received in response to a solicitation issued by the U.S. Department of Energy Office of Science in 2008 and announced on April 27, 2009. Selection of the EFRCs was based on a rigorous merit review process utilizing outside panels composed of scientific experts. Projects at Sandia National Laboratory, the University of Southern California, and the University of California, Santa Barbara, received funding for research into the fundamental science of solid state lighting.
According to the DOE, the EFRC researchers will take advantage of new capabilities in nanotechnology, high-intensity light sources, neutron scattering sources, supercomputing and other advanced instrumentation, much of it developed with DOE Office of Science. The researchers hope to lay the scientific groundwork for fundamental advances in solar energy, biofuels, transportation, energy efficiency, electricity storage and transmission, clean coal and carbon capture and sequestration and nuclear energy. Three of the EFRCs will also be looking to improve solid state lighting technology in projects over the next five years.

UK Government Starts NoveLELs Project
LIGHTimes StaffJuly 26, 2007...The UK Department for Business , Enterprise and Regulatory Reform (DBERR) (formerly
part of Department of Trade and Industry) has begun a vertically integrated
consortium to focus on novel GaN chip technology. The project, named NoveLELS
gets its funding of £3.3 million from the DBERR. The UK Government and
Technology Strategy Board puting up funds in excess of £1.7M of the total
for the project. The project is a partnership among 2 universities, 4 manufacturers,
and 3 large aerospace companies.
Airbus, AgustaWestland, and GE Aviation are the three aerospace giants. IQE
plc, Exxelis Limited, Mesophotonics Limited and Enfis Limited will provide the
manufacturing expertise for the project. Additionally, research teams from University
of Bath and Brunel University will lead the research of novel LED chips and
phosphor technology.
The project aims to commercialize high power solid-state LED sources. The planned
strategy that project leaders hope to utilize for this purpose is to have the

Kyma Wins Army Funding for Research into Non-Polar GaN Substrates
CompoundSemi News StaffOctober 9, 2006...Kyma Technologies of Raleigh, North Carolina USA, reported that the US Army
has selected the company for Phase I funding under the Army’s Small Business
Technology Transfer Research (STTR) program. According to Kyma, the STTR effort’s
ultimate goal will be will be establishing a cost effective supply of non-polar
GaN that can be utilized in military and commercial applications. The company
said it will focus on gaining a better understanding of its current approaches
to making non-polar GaN substrates and also explore new approaches.
GaN experts have theorized that non-polar GaN can improve efficiencies and
performance of optoelectronic and nitride electronics if researchers can find
a cost effective method of producing lower defect density non-polar GaN. LEDs
are among the devices that might benefit from a low defect density non-polar
GaN substrate. So far such performance benefits remain unproven. Dr. Shuji Nakamura
and his team of researchers at University of California Santa Barbara made the
first non-polar and semi-polar LEDs. However the researchers did not see the
expected performance gains from the non-polar GaN. The reason that Dr. Nakamura
cited for the lower than expected performance was that they were not able to
grow the non-polar and semi-polar GaN with low enough defect densities to see
performance gains. (Ref: May
24, 2006 Coverage).
Kyma said its engineers will work with an academic research group headed by
professor Mark Johnson of North Carolina State University (NCSU) and professor
April Brown of Duke University. The company stated that professor Johnson’s
group has already investigated the electrical and structural properties of its
GaN materials, and professor Johnson’s group has also reportedly worked
with Kyma on novel approaches to manufacturing non-polar GaN. Professor Brown
will reportedly extend her current programs in advanced epitaxial growth and
characterization of non-polar GaN materials to Kyma’s low defect density
substrates.
Kyma co-founder and CTO Drew Hanser commented, “This program enables
us to accelerate the development of non-polar GaN materials with ultra-low dislocation
densities and zero stacking faults. Kyma’s non-polar GaN offers a range
of new possibilities in terms of device design and the potential to enable better
device performance across several different semiconductor device types, including
field effect transistors, heterojunction bipolar transistors, and visible and
ultraviolet emitters and detectors.”
Kyma president and CEO Keith Evans added, “Support on this U.S. Army
STTR is an important contribution to our overall effort to provide our customers
with a full suite of best-in-class crystalline GaN and AlN materials and services.
Non-polar GaN represents an exciting addition to our growing product line because
of its strong potential to impact a broad range of military and commercial applications.”

LIGHTimes StaffJune 29, 2006...
Philips Lumileds announced the acheivement of several LED performance records
at 1 Amp. The performance records the company claimed include: luminence of
38 mega nits (Mcd/m2) for white devices. The
company says this is about 60 percent more luminance than automotive halogen
bulbs (about 25 mega nits) achieve. In blue indium gallium nitride (InGaN) devices,
Lumileds boasted a radiance of 200 mW/m2. Then
in green InGaN the company claimed a luminence of 37 mega nits (Mcd/m2).The
company anticipates that their LEDs will go into the brightest LED-based RPTV
that has ever been publicly demonstrated. Lumileds says their advances will
allow increased display size, superior contrast, and color uniformity. Lumileds
hopes to also put the technology to use in automotive headlamps which currently
use halogen bulbs. The company points to additional possible applications such
as aircraft, roadway, and general lighting. Company
