Abstract:
There is provided a gallium nitride substrate having a C plane as a surface with a diameter of not less than 100 mm, the gallium nitride substrate including first regions and second regions having different average values of band-edge emission intensities in a micro photoluminescence mapping at 25° C. in a square region located in the C plane and having sides each having a length of 2 mm, an average value Ibe1a of the band-edge emission intensities of the first regions and an average value Ibe2a of the band-edge emission intensities of the second regions satisfying the following relational expressions (I) and (II): Ibe1a>Ibe2a . . . (I) and 2.1≤Ibe1a/Ibe2a≤9.4 . . . (II).

Claim (Index 2):
The gallium nitride substrate according to  claim 1 , wherein\n a ratio (Ideep/Ibe)1a of the average value of the deep emission intensities of the first regions to the average value of the band-edge emission intensities of the first regions in the micro photoluminescence mapping satisfies a relational expression (III) of (Ideep/Ibe)1a\u22640.47 . . . (III), and a ratio (Ideep/Ibe)2a of the average value of the deep emission intensities of the second regions to the average value of the band-edge emission intensities of the second regions in the micro photoluminescence mapping satisfies a relational expression (IV) of (Ideep/Ibe)2a\u22643 . . . (IV).
