A dipole like strain state is induced by threading edge dislocations emerging at the surface of gallium nitride (GaN) bulk substrates. This local strain is calculated by means of a three-dimensional elastic deformation potential model, taking into account the free surface of the sample. The calculations are in excellent quantitative agreement with the strain state derived from line shifts of the ...
