Implication

Theoretical modeling demonstrates threefold variations in resolution limit under altered optical parameters, highlighting pathways to optimize atomic contrast.

Key Points

To calculate the theoretical resolving power and image contrast of the electron microscope across varied focusing, illumination, and aperture parameters.
Mathematical modeling of resolving power and single-atom image contrast across multiple configurations of focusing, illumination, and aperture size.
Theoretical assessment of spherical aberration effects and correction methods on imaging performance.
Variations in focusing, illumination, and aperture conditions alter the limit of resolution by a factor of approximately 3.
Defocusing and spherical aberration substantially increase the image contrast of an atom.
Image contrast improves overall when the numerical value of the spherical aberration constant is reduced.
