摘要
We propose a new method to obtain surface holographic images at an atomic level by inversion of angle-resolved electron-energy-loss data. The diffraction information is contained in the intensity of a core loss peak measured in fixed directions as a function of the primary beam energy. The results obtained for the model system Ni(111)-p(2 x 2)-K show that our method is valid and promising.
