Irradiation-induced amplification of electric fields at oxide interfaces as revealed by correlative DPC-STEM and DFT
Elizabeth A. Peterson, Dongye Liu, Sean H. Mills +5
Heterointerfaces are ubiquitous in modern devices, found in technologies ranging from microelectronics to structural components for energy applications. Many of these emerging tech…
Surface termination control of charge transfer and band alignment across a semiconductor-crystalline oxide heterojunction
M. Chrysler, J. Gabel, T. -L. Lee +5
Charge redistribution across heterojunctions has long been utilized to induce functional response in materials systems. Here we examine how the composition of the terminating surfa…
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…
Effect of structure and composition on the electronic excitation induced amorphization of LaTiZrO ceramics

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…
Hole-Induced Electronic and Optical Transitions in La1-xSrxFeO3 Epitaxial Thin Films
Le Wang, Yingge Du, Peter V. Sushko +6
We have investigated the electronic and optical properties of epitaxial La1-xSrxFeO3 for x from 0 to 1 prepared by molecular beam epitaxy. Core-level and valence-band x-ray photoem…
Band alignment at epitaxial BaSnO3/SrTiO3(001) and BaSnO3/LaAlO3(001) heterojunctions
Scott A. Chambers, Tiffany C. Kaspar, Abhinav Prakash +2
We have spectroscopically determined the band offsets at epitaxial interfaces of BaSnO3 with SrTiO3(001) and LaAlO3(001). The conduction band minimum is lower in electron energy in…
