  • That is only sort of true - this image is not made of electrons reflected by the nuclei. These are results from TEM imaging, so Transmission Electron Microscopy. The electron detector is placed behind the sample.

    What you are describing is SEM - Scanning Electron Microscopy - in that case, the detector can be placed above the sample, for example (but not limited to) circularly around the beam to measure the backscattered electrons

    In TEM the samples are cut into very thin slices (in the picture you posted it is said to be between 0.8nm - 30nm) and the crystal lattice acts as a diffraction grating for the electron beam. The diffraction pattern can be then used to reconstruct the crystal lattice structure.


  • My point was that if they would be trying to forge the results, they would likely write a better paper. Like, I have never seen nor would I use a phrase like:

    Humankind has long learned that the properties of matter stem from its structure.

    or

    It is the superconductor with the same color as typical superconductors.

    in the results section. It just reads like a student report.

    So while it does not prove whether it is correct or not, it, at least in my understanding, indicates that it is genuine. The explanation might be off, the important step of the synthesis might include adding a teaspoon of luck, but the observations/measurements part I believe. Which is what I meant by the comment.
