• Advances in Materials & Fabrication: GaN (Gallium Nitride)–based HEMTs are gaining traction due to superior performance (higher power densities, better thermal characteristics, ability to operate at higher frequencies). Improved fabrication methods are lowering defects and power loss.

• Aerospace & Defense Demand: HEMTs are increasingly used in radar, satellite, defense communication, and navigation systems. The aerospace & defense segment is projected to record the highest CAGR (≈7.12%) through 2032.

• Consumer Electronics: Growing demand for smaller, faster, more energy-efficient devices (smartphones, RF front ends, IoT devices) is driving volume demand. The consumer electronics segment accounted for 28.12% of the market in 2024.

High-electron-mobility transistors (HEMTs) are field-effect transistors using a heterojunction of materials with different band gaps. HEMTs deliver superior performance in high-frequency applications, thanks to their high gain and low noise features. These devices are invented using advanced epitaxial growth techniques, with exactly engineered layer structures that minimize defects. As a result, HEMTs allow the development of faster, more compact, and energy-efficient semiconductors.

Opportunities include:

• Adoption of HEMTs in electric vehicles (EVs), power conversion, and renewable energy systems.
