Performance improvement of β-Ga2O3 SBD-based rectifier with embedded microchannels in ceramic substrate

Conclusion This study proposed and fabricated a β -Ga 2 O 3 SBD-based rectifier with embedded microchannels in a ceramic substrate for active cooling for the first time. Experimental results demonstrate that this technique can increase the output power from 3.2 to 21.3 W, consuming only 0.9 mW of pu...

Summary:Conclusion This study proposed and fabricated a β -Ga 2 O 3 SBD-based rectifier with embedded microchannels in a ceramic substrate for active cooling for the first time. Experimental results demonstrate that this technique can increase the output power from 3.2 to 21.3 W, consuming only 0.9 mW of pump power. The achievements in this work indicate that embedded cooling offers a powerful technique to suppress the thermal effects on Ga 2 O 3 devices and circuits, thereby improving their electrical performance.
