Gallium nitride (GaN) and silicon carbide (SiC) semiconductors are transforming the aerospace sector due to their superior efficiency, thermal conductivity, and high breakdown voltage compared to traditional silicon. These materials enable power management and radiofrequency (RF) applications to operate at higher temperatures and voltages, making them ideal for harsh aerospace environments. As electric and hybrid aircraft gain traction, GaN and SiC are increasingly favored for their ability to reduce weight, improve energy efficiency, and enhance overall system performance.
The aerospace industry is moving toward electrification, with electric and hybrid aircraft being developed to reduce carbon emissions and fuel dependence. This shift requires advanced semiconductors to support high power conversion, energy storage, and efficient power distribution. Semiconductor devices in this context enable more compact, lightweight, and reliable systems, which are crucial for achieving the high efficiency and environmental sustainability goals of modern aircraft designs.
