This episode will explain:
- What gallium nitride (GaN) is
- The properties that make this material extraordinary
- What advantages GaN has compared to silicon
- How GaN is disrupting the silicon industry
- What challenges there are when developing GaN devices
- The common misconceptions people have about GaN and what aspects are over-hyped
- What it really takes to go from research to a groundbreaking innovation and how much effort goes into producing next generation technologies
- How our future could look like once GaN and next generations batteries are widely deployed
- What types of skills researches need in order to go from research to product
- And finally, the biggest surprises and breakthroughs my guest has had during his career as a scientist
- Gallium nitride (GaN) is a super efficient semiconductor.
- With GaN you lose only about 1% of the energy thay‘re trying to convert vs a silicon device, that loses about 3%. That might not sound like much, but as the vast majority of things include silicon, that‘s huge. Just for reference, you’d save 10% of electricity consumption in the US alone just by using GaN tech.
- GaN electronics is slightly more expensive than silicon. But if you built the whole system using GaN, it's actually much, much cheaper than using silicon in better performance.
- But the overall problem is systemic. Silicon is cheap. It's ubiquitous and companies trust the material. And there’s an entire electronics industry is built on it.
- The main obstacle for widespread adoption is essentially trust. Companies need to get used to this new material and technology. Companies also need to replace and optimize the whole electronics around and existing product. But companies tend to be very conservative. However, this adoption is slowly happening right now. But that takes some time.
- Some companies are trying to grow gallium nitride on top of silicon. The are using the platforms and equipment they already have, but even that still takes time. And so for now manufacturer will have to cope with multiple kinds of semiconductors.
- But it's important to remember, there are some applications where it's better to use silicon than GaN. And there's another material called Silicon Carbide that also has its benefits and drawbacks or gallium oxide. That leaves so much more room to explore.
- It will still take some time before gallium nitride takes over the world, but the market does seem to be growing.
