TL;DR: In this paper, a new Thon ring averaging method was proposed to estimate the defocus and twofold astigmatism of weak phase objects in the presence of spherical aberration.

TL;DR: In this paper, the accuracy of quantitative analysis for Z-contrast images with a spherical aberration (Cs) corrected high-angle annular dark field (HAADF) scanning transmission electron microscope (STEM) using SrTiO3(0.0.1) was systematically investigated.

TL;DR: Sharp diffraction patterns are obtained from well-defined areas on both sides of the interface between a Ti-Si-Ge alloy and Si0.54Ge0.46 using the Cs-correction technique.
Abstract: Selected area diffraction (SAD) from localized areas that are ∼20 nm in diameter has been demonstrated for the first time using a spherical-aberration-corrected transmission electron microscope (C s -corrected TEM). We have succeeded in obtaining sharp diffraction patterns from well-defined areas on both sides of the interface between a Ti-Si-Ge alloy and Si 0 . 5 4 Ge 0 . 4 6 . The errors in the area selection by an SAD aperture are reduced to <2 nm by the C s -correction. The applications of this technique in studies of nanometer-sized materials are discussed.

TL;DR: Development in the field of atomic-resolution electron microscopy is considered, which has developed rapidly in several forms although more work needs to be done to identify standard imaging conditions and to explore novel operating modes.

TL;DR: The radial distribution of the beam-induced charge in thin films is investigated using the contrast transfer properties of the transmission electron microscope and an explanation of the qualitative behavior of the charge density, based on the contamination diffusion theory is proposed.
