    Ernest Rutherford’s model of the atom suggested the atom had a small, compact nucleus surrounded by a cloud of almost weightless electrons. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed in set levels of energy, that is, at set distances from the nucleus. His model was a huge leap forward in making theory fit experimental evidence that other physicists had found over time.…

    The images in this paper were obtained by the detection of secondary electrons that were emitted by atoms excited by the primary electron beam. The primary beam scans in a raster fashion, making horizontal passes across the x-axis one at a time. This allows the detector to display the information into the image on pixel at a time in synchronized manner. The number of secondary electrons that can be detected…
