GaN vs. Silicon: Semiconductor Materials Compared | …
Gallium nitride has a thermal conductivity of 1.3 W/cmK, while silicon has a thermal conductivity of just 1.5 W/cmK. While gallium nitride may not be as well equipped to handle high thermal loads, GaN''s efficiency at comparable voltages actually reduces the thermal loads created by the circuit, meaning it will run cooler than silicon.
