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…
