GaN bandgap physics superiority
3 is bigger than 1. The efficiency delta is not incremental. It is structural. Silicon cannot close this gap through fabrication improvements alone.
The superior bandgap of gallium nitride (GaN) compared to silicon enables higher efficiency and better thermal management in power electronics. This means that as data centers become increasingly important due to AI scaling, the cost savings from using GaN-based components can significantly reduce operational expenses for tech companies, driving demand for these more efficient materials.
The live scenarios suggest a high potential for GaN adoption with multiple factors like an energy crisis and regulatory pushes increasing its viability. However, there is also a notable risk of silicon efficiency improvements or supply disruptions in GaN that could delay or derail the anticipated surge in GaN usage. This indicates that while positive trends are emerging, uncertainties remain significant enough to keep this pillar somewhat conditional.
