Percolation of Ion-Irradiation-Induced Disorder in Complex Oxide Interfaces
Bethany Matthews, Michel Sassi, Christopher M. Barr +5
Mastery of order-disorder processes in highly non-equilibrium nanostructured oxides has significant implications for the development of emerging energy technologies. However, we ar…
Asymmetric Lattice Disorder Induced at Oxide Interfaces
Steven R. Spurgeon, Tiffany C. Kaspar, Vaithiyalingam Shutthanandan +3
Control of order-disorder phase transitions is a fundamental materials science challenge, underpinning the development of energy storage technologies such as solid oxide fuel cells…
Nanoscale Oxygen Defect Gradients in the Actinide Oxides
Steven R. Spurgeon, Michel Sassi, Colin Ophus +3
Oxygen defects govern the behavior of a range of materials spanning catalysis, quantum computing, and nuclear energy. Understanding and controlling these defects is particularly im…
Effect of structure and composition on the electronic excitation induced amorphization of LaTiZrO ceramics
Michel Sassi, Tiffany Kaspar, Kevin M. Rosso +1
Understanding the response of ceramics operating in extreme environments is of interest for a variety of applications. Ab initio molecular dynamic simulations have been used to inv…
