Time-Resolved Phonon Dispersions of Thermally Excited Graphite at the Nanoscale
Mairi McCauley, Christoph T. Koch, Benedikt Haas
Lattice vibrations govern the propagation of heat in materials, and investigating their dynamics through time-resolved phonon dispersion measurements would provide insight into the…
Platform and Framework for Time-Resolved Nanoscale Thermal Transport Measurements in STEM
Mairi McCauley, Joel Martis, Ondrej L. Krivanek +12
Understanding heat transport at the nanometer scale is critical for semiconductor devices, quantum materials, and thermal management of nanostructures, yet direct local measurement…
Real-time surface plasmon polariton propagation in silver nanowires
Wenhua Zhao, Álvaro Rodríguez Echarri, Alberto Eljarrat +7
Electron microscopy techniques such as electron energy-loss spectroscopy (EELS) facilitate the spatio-spectral characterization of plasmonic nanostructures. In this work, a time-de…
Perspective on Atomic-Resolution Vibrational Electron Energy-Loss Spectroscopy
Benedikt Haas, Christoph T. Koch, Peter Rez
Instrumentation developments in electron energy-loss spectroscopy (EELS) in the scanning transmission electron microscope (STEM) one decade ago paved the way for combining milli-el…
Improved Three-Dimensional Reconstructions in Electron Ptychography through Defocus Series Measurements
Marcel Schloz, Thomas C. Pekin, Hamish G. Brown +9
A detailed analysis of ptychography for 3D phase reconstructions of thick specimens is performed. We introduce multi-focus ptychography, which incorporates a 4D-STEM defocus series…
Electron Ptychography Reveals Correlated Lattice Vibrations at Atomic Resolution
Anton Gladyshev, Benedikt Haas, Thomas C. Pekin +4
In this paper we introduce an electron ptychography reconstruction framework, CAVIAR -- Correlated Atomic Vibration Imaging with sub-Angstrom Resolution -- that reveals an entirely…
