%X The effects of cylinder site displacements (site randomness) and cylinder radius variations (size randomness) on photonic band gaps of the photonic crystals, which consist of a graphite lattice of dielectric cylinders, have been discussed by the Order-N method with a supercell technique. The numerical result shows that the variation of the photonic band gaps for the E polarization mode is far more sensitive to disorders with a size randomness than with a site randomness. Furthermore, the influence of the disorder on light extraction of a GaN light-emitting diodes model, which has a disordered photonic crystal slab, has been investigated by three-dimensional finite-difference time-domain method. The numerical result shows that the influence of the disorder is small on light extraction of this light-emitting diodes model, and the influence is random.
