Key Growth Drivers Reshaping the Industry

One of the strongest growth drivers is the transition toward energy-efficient power electronics. GaN and SiC devices can operate at higher voltages, frequencies, and temperatures than many conventional silicon-based solutions, making them attractive for EV charging systems, renewable-energy converters, industrial equipment, data centers, and power supplies. SEMI notes that investment in power and compound semiconductor fabs is being driven by electrification, renewable energy, power efficiency, EVs, industrial automation, and telecommunications.

Artificial intelligence is also creating new demand. Data centers require efficient power conversion and increasingly sophisticated high-speed connectivity. Compound materials are therefore becoming relevant not only in power management but also in RF, optical communications, and high-frequency infrastructure. The broader semiconductor industry is experiencing strong AI-led demand, reinforcing the need for technologies that can improve power efficiency and data transmission performance.
