5*10mm2 SP-face (10-11) Un-doped n-type free-standing GaN single crystal substrate Resistivity < 0.05 Ω·cm Power device/laser wafer
Overview
GaN has many serious advantages over silicon, being more power efficient, faster, and even better recovery characteristics. However, while GaN may seem like a superior choice it won't be replacing silicon in all applications for a while.
Semi-insulating (SI) GaN is known to be transparent from 0.36 µm to~7 µm where an absorption on a second harmonic of optical phonons occurs.

Appendix: The diagram of miscut angle
If δ1= 0 ±0.5°, then (10- 11) plane off angle toward A-Axis is 0 ±0.5°.
If δ2= - 1 ±0.2°, then (10- 11) plane off angle toward C-Axis is - 1 ±0.2°.
