The global gallium nitride (GaN) semiconductor devices market was valued at USD 2.56 billion in 2023 and is expected to experience robust growth with a projected compound annual growth rate (CAGR) of 26.4% from 2024 to 2030. This significant growth can be attributed to GaN's unique properties, such as its ability to deliver high-speed performance, manage larger electric fields, and contribute to lower carbon emissions. These characteristics make GaN semiconductor devices highly effective in a wide range of electronic applications, particularly in sectors where performance, efficiency, and sustainability are critical.
A key factor driving the widespread adoption of GaN technology is its wide band gap of approximately 3.4 eV, which is significantly larger than the 1.2 eV band gap of traditional silicon-based devices. This wider band gap allows GaN devices to operate at higher voltages and temperatures while maintaining superior efficiency. Furthermore, GaN technology offers a higher carrier density and extremely low resistance and capacitance, allowing for operation speeds that are up to 100 times faster than those achieved with silicon devices. These advantages are propelling the use of GaN semiconductor devices across diverse industries, including optoelectronics, automotive, telecommunications, and data centers.
