Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3
Advanced Functional Materials, EarlyView.Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

Electron beam precession for a serial crystallography experiment in a TEM [PDF]
arXivDuring the last few years, serial electron crystallography (Serial Electron Diffraction, SerialED) has been gaining attention for the structure determination of crystalline compounds that are sensitive to the irradiation of the electron beam. By recording a single electron diffraction pattern per crystal, indexing hundreds or even thousands of measured

Valence electron distribution in MgB2 studied by accurate diffraction measurements and first principle calculations [PDF]
arXiv, 2002 We use synchrotron x-ray and precision electron diffraction techniques to determine accurately the structure factors of selected reflections that are sensitive to the valence electron distribution in the superconductor MgB2. These values deviate significantly from calculated structure factors using the scattering factors of free atoms, but agree well ...

Advanced Functional Materials, EarlyView.Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

Re-entrant Layer-by-Layer Etching of GaAs(001)
, 1995 We report the first observation of re-entrant layer-by-layer etching based on {\it in situ\/} reflection high-energy electron-diffraction measurements. With AsBr$_3$ used to etch GaAs(001), sustained specular-beam intensity oscillations are seen at high ...
