Today’s GaN FETs are improving rapidly in size and performance. The benchmark devices are still 300 times away from their theoretical performance limits.
The early GaN adopters needed the speed. Big examples were lidar systems for autonomous cars, drones, and robots, and 4G/LTE base stations. The volume has grown, and now GaN power devices are at a point where the prices are equivalent to the slower, bigger and aging power MOSFET. Thus, it is time for GaN’s frontal assault!

In this episode of PSDtv Alex Lidow, Chief Executive Officer and Co-Founder of Efficient Power Conversion (EPC) is at APEC 2019 in Anaheim and discusses why their GaN on Silicon devices make Silicon now dead.
Last week, Anker debuted a tiny new power brick, crediting its small size with the component it uses instead of silicon: gallium nitride (GaN). It’s the latest example of the growing popularity of this transparent, glass-like material that could one day unseat silicon and cut energy use worldwide.
This scientist got his Ph.D 40 years ago who saved the world's 15% energy consumption at one time. He is continuing his journey of innovations now in discovering silicon's replacement material for humankind.
My father always taught me that the true worth of an individual is measured based on their contribution to society. As I entered graduate school in 1975 I knew my passion was in the field of semiconductors, and I felt my best contribution to society would come from finding a successor to silicon. I did my graduate work in Gallium Arsenide, but realized by the time I received my ...
As deep learning proliferates, the question of data center power density is once again on the rise, creating new business opportunities for specialized cloud services, hosted in facilities that can support north of 30 kW per rack, and companies in the power conversion space, who can tackle the density issue by making systems more energy efficient. Replacing silicon as the semiconductor material in power conversion chips with gallium nitrate, or GaN, leads to much smaller and more energy efficient devices that provide much faster switching.

Silicon -- the core ingredient in semiconductors and the driving force behind the electronics industry -- is reaching its limit, says Alex Lidow, CEO of Efficient Power Conversion Corporation. 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. "This is the first
time that there is a semiconductor that is both lower cost and has a higher performance than silicon," Lidow says.

The effort to take advantage of gallium nitride is partly a response to technical and economic factors that have slowed improvement in silicon-based chips. While companies are still finding ways to fabricate smaller transistors in silicon, reductions in cost and power consumption have been more difficult to achieve. But gallium-nitride circuits can switch on and off much more quickly than silicon and handle higher voltages, said Alex Lidow, EPC’s chief executive. That makes the material particularly good for chores that involve power conversion.

Power conversion involves creating tiny devices that convert electricity from one form to another, enabling all manner of electrical gadgets to function. Till now, silicon had been the preferred medium for power conversion processors, but as that element reaches the limits of its efficiency, attention has focused on new materials.
