Laser-based aberration corrector
Zdeněk Nekula, Thomas Juffmann, Andrea Konečná
Aberration correctors are essential elements for achieving atomic resolution in state-of-the-art electron microscopes. Conventional correctors are based on a series of multipolar e…
Efficient nanoscale imaging of solid-state phase transitions by transmission electron microscopy demonstrated on vanadium dioxide nanoparticles
Michal Horák, Peter Kepič, Jiří Kabát +5
We present annular dark field scanning transmission electron microscopy (ADF-STEM) as an efficient, fast, and non-destructive nanoscale tool for monitoring solid-state phase transi…
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…
Simultaneous imaging of dopants and free charge carriers by STEM-EELS
Hongbin Yang, Andrea Konečná, Xianghan Xu +4
Doping inhomogeneities in solids are not uncommon, but their microscopic observation and understanding are limited due to the lack of bulk-sensitive experimental techniques with hi…
Correlative electron and light spectroscopy of strongly-coupled mid-infrared plasmon and phonon polaritons
Pavel Gallina, Andrea Konečná, Jiří Liška +2
The ability to control and modify infrared excitations in condensed matter is of both fundamental and application interests. Here we explore a system supporting low-energy excitati…
Nanoscale Nonlinear Spectroscopy with Electron Beams
Andrea Konečná, Valerio Di Giulio, Vahagn Mkhitaryan +2
We theoretically demonstrate the ability of electron beams to probe the nonlinear photonic response with nanometer spatial resolution, well beyond the capabilities of existing opti…
