Analysis of Electron Wave Scattering by Nano Grating Structure
We develop an exact method to analyze the scattering of electron wave by nano grating structure. To our best knowledge, this is the first analysis for the nano grating structure investigated. The method combines the building block approach of multimode network theory with a rigorous mode-matching procedure. Symmetry properties of the structure are employed to simplify the analysis. Numerical results are provided for discussions. The higher the incident electron wave energy, the more propagating Floquet modes. At low incident electron wave energies, we find that only few Floquet modes can propagate in the grating structure. The accuracy of numerical calculation is checked by the conservation of probability, i.e. the sum of the reflected and transmitted electron wave probabilities is equal to the total incident electron wave probability.
