Structure and Phase Transitions of Metastable Hexagonal Uranium Thin Films
Rebecca Nicholls, Chris Bell, Johann Bouchet +2
We report a simple technique for the synthesis of uniaxially textured, metastable hexagonal close-packed-like uranium thin films with thicknesses between 175-2800 Å. The initial st…
Accurate and efficient structure factors in ultrasoft pseudopotential and projector augmented wave DFT
Benjamin X. Shi, Rebecca J. Nicholls, Jonathan R. Yates
Structure factors obtained from diffraction experiments are one of the most important quantities for characterizing the electronic and structural properties of materials. Methods f…
Direct Imaging of Charge Redistribution due to Bonding at Atomic Resolution via Electron Ptychography
Gerardo T. Martinez, Benjamin X. Shi, Timothy C. Naginey +6
Phase imaging in electron microscopy is sensitive to the local potential, including charge redistribution from bonding. We demonstrate that electron ptychography provides the neces…
Theory of momentum-resolved phonon spectroscopy in the electron microscope
R. J. Nicholls, F. S. Hage, D. G. McCulloch +3
We provide a theoretical framework for the prediction and interpretation of momentum dependent phonon spectra due to coherent inelastic scattering of electrons. We complete the app…
