Global Gallium Nitride (GaN) Industry Chain and Technology Roadmap
May 12, 2025
I. Gallium Nitride (GaN)
Gallium nitride (GaN) is an inorganic chemical compound with the formula GaN, composed of gallium (Ga) and nitrogen (N). As a third-generation semiconductor material, it typically exists as a white or slightly yellow solid powder. Key material properties include:
- Structural stability under extreme conditions
- High melting point (>1700°C)
- High voltage resistance (breakdown field ~3.3 MV/cm)
- Radiation tolerance (effective for space and nuclear environments)
This wide-bandgap semiconductor exhibits superior performance in harsh operating environments compared to traditional silicon-based materials, making it critical for applications in power electronics, radio frequency (RF) systems, and optoelectronics.
II. Market Size and Growth Trends
With the continuous expansion of gallium nitride (GaN) technology from consumer electronics into high-power applications such as electric vehicles (EVs), photovoltaic energy storage, and data centers, the global GaN power device market is experiencing accelerated growth:
Market Data:
- In 2022, the market size reached 180 million USD, projected to hit 1.33 billion USD by 2026, with a compound annual growth rate (CAGR) of 65% .
- Consumer electronics remains the dominant market segment, accounting for approximately 146 million USD in 2022, expected to surge to 1.307 billion USD by 2028 (Yole Développement).
Application Expansion:
The application scope has broadened from traditional smartphone fast charging and power adapters to mid-to-high-power scenarios including new energy vehicle onboard chargers (OBCs), telecommunications base stations, photovoltaic inverters, data center servers, industrial power supplies, and energy storage systems.
