50.8 ± 1 mm 2-inch Free-standing U-GaN/SI-GaN Substrates (1-100) ± 0.5o, 16 ± 1 mm
2inch C-face Un-doped n-type free-standing GaN single crystal substrate Resistivity < 0.1 Ω·cm Power device/laser wafer
Overview
GaN Breakdown Field
A higher breakdown field means that gallium nitride is superior
over silicon in high voltage circuits such as high-power products.
Manufacturers and engineers can also use GaN in similar voltage
applications while maintaining a significantly smaller footprint.
