We introduce a novel method for the simulation of the impact scattering in vibrational scanning transmission electron microscopy electron energy loss spectroscopy simulations. The phonon-loss process is modeled by a combination of molecular dynamics and elastic multislice calculations within a modified frozen phonon approximation. The key idea is thereby to use a so-called δ thermostat in the classical molecular dynamics simulation to generate frequency dependent configurations of the vibrating… Expand
The frequency-resolved frozen phonon multislice method and its application to vibrational EELS using parallel illumination
We explore the capabilities of the frequency-resolved frozen phonon multislice method introduced in Phys. Rev. Lett. 124, 025501 (2020) to model inelastic vibrational scattering in transmissionExpand
Simulations of angle- and spatially-resolved vibrational electron energy loss spectroscopy for a system with a planar defect

Lattice resolution of vibrational modes in the electron microscope.
It is shown that Umklapp scattering from the second Brillouin Zone back to the first BrillouIn Zone is necessary for lattice resolution with the on axis detector and that it is therefore reasonable to attribute the latticeresolution to the phonon scattering. Expand
Contrast reversal in atomic-scale phonon spectroscopic imaging

Simulation of thermal diffuse scattering including a detailed phonon dispersion curve.
The phonon dispersion curve yields a small additional oscillatory structure in the thermal diffuse scattering (TDS) pattern, which does not produce significant changes in the annular dark field scanning transmission electron microscope image signal, but could have a large impact on convergent beam measurements of bond charges.
