Entegris Ships Gas Purification Systems Used in LED Manufacturing Nov 19, 2009
Lextar, a leading Taiwan-based manufacturer of super high-brightness LED (HBLED) products, is purchasing separate Aeronex gas purification systems for purifying nitrogen, hydrogen and ammonia used in the gallium nitride-based LED manufacturing process. The Aeronex systems remove a variety of contaminants including moisture and oxygen down to the parts-per-billion level from the process gases used during the metal organic chemical vapor deposition (MOCVD) process.

New Nanowires May Contribute To Highly Efficient Solar Cells Nov 14, 2009
"We have changed the recipe for producing nanowires. This means that we can produce nanowires that contain two different semiconductors, namely gallium indium arsenide and indium arsenide. It is a big breakthrough, because for first time on a nanoscale, we can combine the good characteristics of the two materials, thus gaining new possibilities for the electronics of the future," explains Peter Krogstrup ... "Different materials capture energy from the sun in different and quite specific... (Science Daily)
The rise of thin-film solar power: Leaner and cheaper Oct 27, 2009
But firms such as Nanosolar, which is building factories in California and Germany, believe that a combination of copper, indium, gallium and selenium known as CIGS will prove cheaper to produce on a mass scale. Researchers at the University of California, meanwhile, hold out great hopes for cells made of organic chemicals. (The Economist)
New One-Atom Thick Material Has Scientists Abuzz Jul 15, 2009
0 Researchers at The University of Manchester have found that electrons move more easily in graphene than all other materials, including gold, silicon, gallium arsenide and carbon nanotubes. Apr 17, 2008. (Newsmax)
A Sonic Boom In The World Of Lasers Jun 19, 2009
This is made out of around 50 super-thin sheets of two alternating semiconductor materials, Gallium Arsenide and Aluminium Arsenide, each layer just a few atoms thick. When stimulated by a power source (a light beam), the phonons multiply, bouncing back and forth between the layers of the lattice, until they escape out of the structure in the form of an ultra-high frequency phonon beam.

Oclaro(TM) Introduces New Focus(TM) 1064nm High Power Laser for Raman Spectroscopy Applications Jun 17, 2009
The high power laser is enabled by the GaAs (gallium arsenide) chips manufactured at the company's state-of-the-art facility in Zurich. The chip design also leverages the same technology as the market-leading Oclaro terrestrial and submarine telecom amplifier and pump portfolios, including the 750mW ultra high power pump and the OceanBright(TM) submarine pump.

Good neighbor in southwest Portland wore many hats helping others Apr 19, 2009
He received his doctorate in "dislocation-free growth" in the element gallium. He made a beautiful model of the crystal, showing how the electronic connection works. (OregonLive, OR -- News)
Medical Micro-robots Made As Small As Bacteria Apr 19, 2009
ABFs are fabricated by vapor-depositing several ultra-thin layers of the elements indium, gallium, arsenic and chromium onto a substrate in a particular sequence. They are then patterned from it by means of lithography and etching. (Science Daily)
New Radiation-free Targeted Therapy Detects And Eliminates Breast Cancer Tumors In Mice Apr 1, 2009
31, 2009) Combining a compound known as a gallium corrole with a protein carrier results in a targeted cancer therapy that is able to detect and eliminate tumors in mice with seemingly fewer side effects than other breast-cancer treatments, says a team of researchers from the California Institute of Technology (Caltech), the Israel Institute of Technology (Technion) and the Cedars-Sinai Medical Center ... "The striking thing about gallium corroles is that they apparently kill cancer cells in the... (Science Daily)
Lighting: A brilliant new approach Mar 21, 2009
But the biggest cost reduction will come from breakthroughs like that recently made by the Centre for Gallium Nitride at Cambridge University, England. Gallium nitride is a semiconductor used to create bright-blue LEDs ... Most of the white LEDs now on the market are based on gallium nitride. (The Economist)
