| Abstract: | Fist, an applicable Schrodinger Equation for the electron movement in the heterogenity structure ofthe column symmetric super-Lattice is established. Then the dispersion relations of the electron energyspectrum by adopting the micro-method is discussed. And the existence of alternation between conductiveband and forbidden band in the electron energy spectrum of the column super-lattice is proved. At last,the thickness of the couxal heterogenity layer and the influence of the radius of the heterogenity systemcore on the electron energy spectrum are discussed. |
