Keywords:

  • STEM development - of scanning transmission electron microscopy;
  • field of nanotechnology - occupying domain, from atomic size to about 100 nm;
  • Crewe revolution, STEM - solving information problem, ‘annular dark field detector’ or ‘ADF’;
  • scattering into ADF - from Rutherford scattering, by atomic nuclei sampled by beam;
  • basic configuration of Crewe's instrument - in all modern dedicated STEM;
  • electron optical simplicity of STEM - kind of ‘radar’ beam, scanning regions of interest;
  • single-lens conventional microscope (CTEM) - and single-lens scanning transmission microscope (STEM);
  • STEM, collection of CBED patterns, probe position - diffractive imaging, ‘Ptychography’;
  • EELS, analysis at the highest possible spatial resolution - limited, by probe size and ‘impact parameter’;
  • beam damage and beam writing - limitations of STEM, specimen damage by fast electron beam
