In the present invention, the self-organized dots are formed by the constructive interference formed in the surface of the ITO film, where includes higher energy to break the In—O and Sn—O bonds and then form the In—In bonds. Therefore, the dots have higher surface current greater than other disconstructive regions of the ITO film.
