Yet even at this early stage he thinks gallium nitride-on-silicon LEDs would make commercial sense.
Most of the white LEDs now on the market are based on gallium nitride.
Gallium Arsenide and Gallium Nitride are preferred for LEDs, certain photovoltaics, and some very high frequency radio applications.
Kim said his staff has figured out a way to create the desirable combination of gallium-nitride top layer on a gallium-nitride substrate.
The files detail an amplifier device using gallium nitride (GaN), technology that has both commercial and potential military uses, according to the FT.
Gallium nitride, or GaN, converts electrical impulses to light and is grown on the surface of wafers made from sapphire or silicon carbide.

But the biggest cost reduction will come from breakthroughs like that recently made by the Centre for Gallium Nitride at Cambridge University, England.
At present these LEDs are made in machines similar to those used to make silicon chips, by depositing layers of gallium nitride on sapphire-based wafers.
LEDs are currently made with a crystalline material called gallium nitride.

And, whereas most Gallium Nitride (GaN) LEDs on the market measure just two inches in size, Sammy's technique could result in displays about 400 times larger.

Holding a doctorate in electrical engineering, Shane Todd worked for his prominent employer, helping to develop faster, more powerful semiconductors by using the compound gallium nitride.
Because the atomic lattice structure of gallium nitride is better matched to sapphire than it is to silicon, making LEDs on silicon without distortions has proved extremely tricky.
Gallium nitride is a semiconductor used to create bright-blue LEDs.
After his death, Todd's parents found that his hard drive contained a proposal between the Singapore outfit and a prominent Chinese telecom firm, Huawei, to build a powerful amplifier using gallium nitride technology.
Gallium-nitride is manmade and not found in nature, and historically, LEDs are made by growing a gallium-nitride layer on top of a base material, which is typically sapphire or, more recently, silicon carbide.
What Transphorm is doing is making new kinds of power conversion devices, based on a material called gallium nitride (a substance best known for its use in LED lighting), which it embeds in modules and sells to equipment manufacturers.

Today, the Samsung Advanced Institute of Technology announced that its engineers have successfully created "single crystalline Gallium Nitride on amorphous glass substrates" -- an achievement that would allow the manufacturer to produce jumbo-sized LEDs from normal glass, including window panes.

Samsung's 7.1 Channel Home Theater System (model HT-F9750W) was created to be the perfect counterpart for Samsung's 2013 TVs, with a Gallium Nitride (GaN) amplifier that delivers pure sound, and design and usability features that bring home a totally seamless experience.
ENGADGET: Samsung introduces its CES audio hardware, claims a world first
What Colin Humphreys and his colleagues at Cambridge have come up with is a reliable way to deposit gallium nitride on much cheaper silicon wafers, which they estimate could cut production costs to a tenth of what they are at the moment.
Nakamura created the LED out of gallium-nitride, which became the semiconductor for making white LED lights today.
