Definitions
- the present invention relates to a three-dimensional periodic structure and a method for manufacturing the same.
- the cloth has an interference effect on electron waves of a wavelength corresponding to the lattice constant. That is, when the wavelength of the electron wave is very close to the 'potential period' of the crystal, reflection occurs due to three-dimensional diffraction (Bragg diffraction). Due to this phenomenon, electrons contained in a specific energy region are prohibited from passing through. This is the formation of the electronic band gap used for semiconductor devices and the like.
