Overview

There are three main substrates that are used with GaN - Silicon Carbide (SiC), Silicon (Si) and Diamond. GaN on SiC is the most common of the three and has been used in various applications in the Military and for High Power Wireless Infrastructure Applications. GaN on Si is a newer substrate whose performance is not as good as SiC but it is more economical. GaN on Diamond is the best performing, however since it is new and relatively expensive, applications, where this has been used, are limited. We have compared all three GaN Substrates in the table below.

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°.
