2-Inch Free-Standing N-GaN Substrates N Face Surface Roughness 0.5 ~1.5 μm (Single Side Polished)
2inch C-face Si-doped n-type free-standing GaN single crystal substrate Resistivity < 0.05 Ω·cm Power device/laser wafer
Overview
These GaN wafers realize unprecedented ultra-bright laser diodes and high-efficiency power devices for use in projector light sources, inverters for electric vehicles, and other applications.
Gallium nitride can also be synthesized by injecting ammonia gas into molten gallium at 900-980 °C at normal atmospheric pressure.
