Atomic resolution mapping of localized phonon modes at grain boundaries
Benedikt Haas, Tara M. Boland, Christian Elsässer +5
Phonon scattering at grain boundaries (GBs) is significant in controlling nanoscale device thermal conductivity. However, GBs could also act as waveguides for selected modes. To me…
A New Path to Nanoscale Cellular Analysis with Monochromated Electron Energy-Loss Spectroscopy
Jordan A. Hachtel, Jacek Jakowski, Jingsong Huang +6
High-spatial-resolution vibrational spectroscopy is one of the principal techniques for nanoscale compositional analysis in biological materials. Here, we present a new method for…
Localized Phonon Densities of States at Grain Boundaries in Silicon
Peter Rez, Tara Boland, Christian Elsässer +1
Since it is now possible to record vibrational spectra at nanometer scales in the electron microscope it is of interest to explore whether defects such as dislocations or grain bou…
Impact of Aliovalent Alkaline-Earth Metal Solutes on Ceria Grain Boundaries: A Density Functional Theory Study
Tara M. Boland, Peter Rez, Peter A. Crozier +1
Ceria has proven to be an excellent ion-transport and ion-exchange material when used in polycrystalline form and with a high-concentration of aliovalent doped cations. Despite its…
Vibrational Spectroscopy at Atomic Resolution with Electron Impact Scattering
Kartik Venkatraman, Barnaby D. A. Levin, Katia March +2
Atomic vibrations control all thermally activated processes in materials including diffusion, heat transport, phase transformations, and surface chemistry. Recent developments in m…
Dose, exposure time, and resolution in Serial X-ray Crystallography
D. Starodub, P. Rez, G. Hembree +8
The resolution of X-ray diffraction microscopy is limited by the maximum dose that can be delivered prior to sample damage. In the proposed Serial Crystallography method, the damag…
