Scanning transmission electron microscopy (STEM), where a converged probe is scanned over sample's surface and an imaging, diffraction, or spectroscopic signal measured as function of position, extremely powerful tool for materials characterization. The widespread adoption hardware aberration correction, direct detectors, computational imaging methods have made STEM one the most important tools atomic-resolution science. Many these rely on accurate diffraction simulations in order to...

Low-voltage transmission electron microscopy (≤80 kV) has many applications in imaging beam-sensitive samples, such as metallic nanoparticles, which may become damaged at higher voltages. To improve resolution, spherical aberration can be corrected for a scanning microscope (STEM); however, chromatic then dominate, limiting the ultimate resolution of microscope. Using image simulations, we examine how corrector, different objective lenses, and beam energy spreads each affect quality gold...
The transmission electron microscope (TEM) has become an essential tool for innovation in nanoscience, material science, and biology. Despite these instruments being widely used across both industry academia, academics may hesitate to propose substantial modifications the optical setup due instrument's significant purchase price, fear of voiding service contract, or downtime unacceptable shared user facilities. For found industry, similarly risk-reward balance makes substantive untenable....
