Lessons from the harmonic oscillator -- a reconciliation of the Frequency-Resolved Frozen Phonon Multislice Method with other theoretical approaches
Paul M. Zeiger, Juri Barthel, Leslie J. Allen +1
We compare the Frequency-Resolved Frozen Phonon Multislice (FRFPMS) method, introduced in Phys. Rev. Lett. 124, 025501 (2020), with other theoretical approaches used to account for…
Control of the phonon band gap with isotopes in hexagonal boron nitride
Paul Zeiger, Jordan Hachtel, Dominik Legut +5
The isotopic mass of constituent elements of materials has a well-known effect on the energy of vibrational modes. By means of monochromated scanning transmission electron microsco…
Atomic resolution mapping of localized phonon modes at grain boundaries
Benedikt Haas, Tara M. Boland, Christian Elsässer +5
Phonon scattering at grain boundaries (GBs) is significant in controlling nanoscale device thermal conductivity. However, GBs could also act as waveguides for selected modes. To me…
Measurement of atomic modulation direction using the azimuthal variation of first order Laue zone electron diffraction
Aurys Silinga, Christopher S. Allen, Juri Barthel +2
We show that diffraction intensity into the First Order Laue Zone (FOLZ) of a crystal can have a strong azimuthal dependence, where this FOLZ ring appears solely because of unidire…
3D sub-nanoscale imaging of unit cell doubling due to octahedral tilting and cation modulation in strained perovskite thin films
Magnus Nord, Andrew Ross, Damien McGrouther +5
Determining the 3-dimensional crystallography of a material with sub-nanometre resolution is essential to understanding strain effects in epitaxial thin films. A new scanning trans…
The Effect of Intra-Layer Bonding on Electron-Optical Phase Images of Few-Layer WSe2
Sven Borghardt, Florian Winkler, Zeila Zanolli +4
The quantitative analysis of electron-optical phase images recorded using off-axis electron holography often relies on the use of computer simulations of electron propagation throu…
