Why is it important?
There are so many papers related to AlGaN-based devices. However, it would be difficult to compare except the output power or external quantum efficiency. This paper show the advantage of sapphire substrate with a high off-cut angle on the basis of similar device structure.
Perspectives
The practical improvements for the industrial applications are described.
