Gallium Nitride Epitaxial Wafers See Rising Adoption Across High-Power Applications

 

The global GaN (Gallium Nitride) epitaxial wafers market was valued at US$ 267.8 Mn in 2022 and is projected to expand at a CAGR of 7.8% from 2023 to 2031, reaching US$ 525.2 Mn by the end of 2031. GaN epitaxial wafers are foundational to the fabrication of advanced power electronics, RF devices, and optoelectronic systems. The market is gaining significant traction due to the growing demand for energy-efficient electronics and next-generation communication systems, particularly 5G.

Industry experts highlight the accelerating use of GaN-based components across sectors such as telecommunications, automotive, consumer electronics, and industrial applications. This momentum is driven by the material’s superior properties—such as high electron mobility, thermal conductivity, and voltage tolerance—making it an essential enabler for miniaturization and high-performance electronics. GaN epitaxial wafers are expected to play a central role in reshaping the semiconductor landscape over the next decade.

 

Market Drivers & Trends

One of the primary market drivers is the growing demand for energy-efficient power electronics. GaN-based devices offer reduced energy losses, higher power densities, and better performance compared to traditional silicon-based devices.
