Very low energy scanning transmission electron microscopy is emerging as a novel tool for examination of ultrathin foils to learn more about the electron structure of solids. The electron micrographs provide image contrasts governed by the effective thickness of the sample proportional to the inner potential and at lowest energies the local density of electron states in the direction of impact of the electron wave starts to dominate. The optical methods are used during the sample preparation. The laser confocal microscope Olympus Lext OLS 3100 was used for preliminary observations of the 3 nm C foil prepared by magnetron sputtering in nitrogen atmosphere on a flat glass covered by a disaccharide layer.
