5*10mm2 Free-Standing GaN Single Crystal Substrate (20-21)/(20-2-1) Un-Doped SI-Type
5*10mm2 SP-face (20-21)/(20-2-1) Un-doped SI-type free-standing GaN single crystal substrate Resistivity > 106 Ω·cm RF devices wafer
Overview
Gallium Nitride is a semiconductor technology used for high power, high-frequency semiconductor applications. Gallium Nitride exhibits several characteristics that make it better than GaAs and Silicon for various high power components. These characteristics include a higher breakdown voltage and better electrical resistivity.

Appendix: The diagram of miscut angle
If δ1= 0 ±0.5°, then (20-21)/(20-2- 1) plane off angle toward A-Axis is 0 ±0.5°.
If δ2= - 1 ±0.2°, then (20-21)/(20-2- 1) plane off angle toward C-Axis is - 1 ±0.2°.
