Gallium Nitride (GaN) possesses a wide band gap that makes the device more compact and capable of handling larger electric fields. As GaN possesses a wider band gap (approximately 3.4 eV) in contrast to silicon (1.2 eV), it facilitates higher carrier density, exceptionally low resistance, and capacitance, contributing to 100 times faster speeds. In addition, the integration of GaN technology across diverse sectors such as optoelectronics, automotive, and data centers has been instrumental in driving the growth of the market.
The automotive sector is currently experiencing a significant transformation toward electrification, with GaN semiconductor devices emerging as crucial components driving this change. Leveraging GaN’s exceptional efficiency and robust power handling capabilities, various applications within electric vehicles, including onboard chargers, DC-DC converters, and power inverters, are being optimized for enhanced performance. As the global demand for electric vehicles escalates, the market for GaN semiconductor devices is positioned for substantial expansion, playing a pivotal role in accelerating the widespread adoption of electric transportation solutions. This evolution not only underscores the automotive industry’s commitment to sustainability but also signifies a paradigm shift toward cleaner and more efficient mobility solutions on a global scale.
