Thermal diffuse scattering in sub-angstrom quantitative electron microscopy-phenomenon, effects and approaches.
This paper reviews the recent progress in the following areas. (1) In quantitative high-resolution transmission electron microscopy, the theoretically calculated images usually give better contrast than the experimentally observed ones although all of the factors have been accounted for. This discrepancy is suggested due to thermal diffusely scattered (TDS) electrons, which were not included in...
متن کاملPrecision Limits to STEM Imaging from Dynamical Scattering and Channeling of Sub-Angstrom Electron Probes
Precision smaller than the resolution is routinely achieved in electron microscopy, with 3-5 pm being the best reported for STEM [1], compared to 1-3 pm for TEM [2]. The signal to noise ratio (SNR) introduces the fundamental precision limit in STEM and TEM images. However, before the fundamental limit is reached, practical limits are usually encountered, such as image distortions caused by inst...
متن کاملAn efficient way of including thermal diffuse scattering in simulation of scanning transmission electron microscopic images.
We propose an improved image simulation procedure for atomic-resolution annular dark-field scanning transmission electron microscopy (STEM) based on the multislice formulation, which takes thermal diffuse scattering fully into account. The improvement with regard to the classical frozen phonon approach is realized by separating the lattice configuration statistics from the dynamical scattering ...
متن کاملAn optical potential approach to incoherent multiple thermal diffuse scattering in quantitative HRTEM
The theory for the absorption potential (or optical potential) in electron scattering was first proposed by Yoshioka in 1957 based on an approximation that the Green’s function is replaced by its form in free-space. This approximation has dramatically simplified the calculation, but the function of the optical potential has been partially lost. In this paper, a rigorous theoretical proof is giv...
متن کاملThree-dimensional quantitative force maps in liquid with 10 piconewton, angstrom and sub-minute resolutions.
We develop a bimodal force microscopy method to map the three-dimensional force fields and their time-evolution on a variety of solid-water interfaces. The force maps show an oscillatory decaying force perpendicular to the solid surface with a 0.3 nm periodicity. The technique enables the three-dimensional imaging and mapping of the hydration layers and forces on mica and protein GroEL surfaces...
