Magnon spectroscopy in the electron microscope
Demie Kepaptsoglou, José Ángel Castellanos-Reyes, Adam Kerrigan +9
The miniaturisation of transistors is approaching its limits due to challenges in heat management and information transfer speed. To overcome these obstacles, emerging technologies…
Systematic Absences of Optical Phonon Modes in Phonon Dispersion Measured by Electron Microscopy
Aowen Li, Paul Zeiger, Zuxian He +4
Phonon dispersion is widely used to elucidate the vibrational properties of materials. As an emerging technique, momentum-resolved vibrational spectroscopy in scanning transmission…
Inelastic electron scattering at large angles: the phonon polariton contribution
Hongbin Yang, Paul Zeiger, Andrea Konečná +11
We explore the inelastic electron scattering in SrTiO3, PbTiO3, and SiC in their phonon energy range, challenging the assumption that phonon polaritons are excluded at large angles…
Dynamical theory of angle-resolved electron energy loss and gain spectroscopies of phonons and magnons in transmission electron microscopy including multiple scattering effects
José Ángel Castellanos-Reyes, Paul Zeiger, Ján Rusz
We present a method for computing angle-resolved electron-energy-loss and gain spectroscopies for phonon and magnon excitations in transmission electron microscopy. Fractional scat…
