Silicon is Reaching its limit. What''s Next?
Silicon will always dominate. In the long term, for power semiconductors, silicon will dominate in the low-voltage range (0-80 volts). GaN has benefits from 80-650 volts, and silicon carbide offers the best performance above 650 volts.” – Richard Eden, principal
