Advancements in Ga₂O₃: A Game Changer for Power Electronics
Gallium oxide (Ga₂O₃) is emerging as a leading ultra-wide bandgap semiconductor, with a bandgap energy of 4.7-4.9 eV, surpassing SiC and GaN. Its potential applications in high-voltage power electronics could revolutionize efficiency in electric vehicles and renewable energy systems.

Gallium oxide (Ga₂O₃), particularly in its β phase, offers a bandgap energy of 4.7-4.9 eV, making it suitable for high-voltage applications (>1 kV). Projected Baliga's figure of merit (BFoM) values for β-Ga₂O₃ significantly exceed those of silicon carbide (SiC) and gallium nitride (GaN), promoting its use in power devices.
However, lower thermal conductivity than SiC and GaN presents thermal management challenges. PVD methods, including sputtering and pulsed laser deposition (PLD), are being explored for Ga₂O₃ growth, providing flexibility and cost-effectiveness.
These techniques allow for precise control over film properties, essential for enhancing device performance. VON ARDENNE is advancing these thin-film deposition technologies, which may reduce manufacturing costs while improving integration into production lines.
