Scope
This standard specifies the method for measuring the lattice constant of epitaxial films of Group III nitrides using high-resolution X-ray diffraction testing.
This standard is applicable to the measurement of the lattice constant of nitride (Ga, In, Al)N single-layer or multi-layer heteroepitaxial films grown on oxide substrates (Al2O3, ZnO, etc.) or semiconductor substrates (GaN, Si, GaAs, SiC, etc.). The measurement of the lattice constant of other heteroepitaxial films can also refer to this standard.
