Demand for GaN power FET for radars and satellite microwave communications base stations is growing steadily, both for new equipment and replacement of electron tubes.
In response to these demands,we have developed a wide band gap semiconductor substrate with gallium nitride(GaN) as the next generation semiconductors.
Gallium Nitride: N type, p type and semi-insulating gallium nitride substrate and template or GaN epi wafer for HEMT with low Marco Defect Density and Dislocation Density for LED, LD or other application.
Yaskawa Electric Corporation has developed a powerconditioner for residential solar power that uses gallium nitride(GaN) semiconductors instead of silicon semiconductors, and is be the first in the world to put this on the market as of January 2015.
In addition to traditional sapphire, silicon(SI), silicon carbide(sic) substrate materials, zinc oxide(ZnO)and gallium nitride(Gan) are also the focus of the current LED chip research.
The business that Sumitomo Chemical will acquire from Hitachi Metals includes those of compound semiconductor materials,such as gallium nitride(GaN) substrates, GaN epiwafers, and gallium arsenide(GaAs) epiwafers.
The process can be used with the gallium nitride that's used in LED lighting and can also boost efficiency in other semiconductor products, including solar cells.
This, plus transitioning to new materials such as gallium nitride in the power conversion systems can reduce overall power consumption by 20% and increase server densities by 30-40.
He is currently working with Efficient Power Conversion Corporation, where, as Director of Applications Engineering, he develops applications, circuits,and methods to maximize the benefit of gallium nitride(GaN) power transistors.
His Los Angeles-based company is investigating the capacity of gallium nitride(GaN) to disrupt the $400 billion(£277bn) silicon industry with its improved powers of semiconducting.
In the first article in this series, how gallium nitride(GaN)-on-silicon low voltage power devices have enabled many new applications, such as light detection and ranging(LiDAR), envelope tracking, and wireless power was discussed.
With the emergence of the 48V bus architecture,a new hybrid converter using gallium nitride(GaN) transistors can be employed which achieves a peak efficiency that exceeds 95% and with 225W/in3 power density.
Using this method, in 1992, the specific resistance of heat-treated GaN thin film was improved to 2 Ohm-cm- smaller than usual by more than a factor of 100,000- and the superior p-type layer was successfully obtained where the hole mobility by Hall measurement was 10 cm2/Vs14.
The test results described in thisninth reliability report show that EPC gallium nitride products in wafer level chip-scale packages have the superior reliability, cost, and performance to displace silicon as the technology of choice for semiconductors.
Based on this, they measured the electrical characteristics of 10 kV electron irradiated Mg doped GaN thin film and found that the resistivity decreased by a factor of 10,000 to 35 Ohm-cm, and confirmed that GaN film is clearly p-type by its Hall effect measurement.
Gallium Nitride(GaN) transistors and integrated circuits, which EPC sells to almost every major electronics company in the world, allow companies to make smaller, faster and more power-efficient products compared with those made from silicon.
