Therefore, study on the strain of the InGaN / GaN material is necessary.
Theory For one element and the two element, the lattice constant of the material obtained by consulting table of physical constants and international powder diffraction database.
The lattice constant of three element and the four element of the material can be obtained according to the Vegard law, such as the lattice constant of three element material can be obtained by linear interpolation from lattice constant of two element materials: .
