3-D Tracking and Visualization of Hundreds of Pt-Co Fuel Cell Nanocatalysts During Electrochemical Aging
Yingchao Yu, Huolin L. Xin, Robert M. Hovden +5
We present an electron tomography method that allows for the identification of hundreds of electrocatalyst nanoparticles with one-to-one correspondence before and after electrochem…
Data Processing For Atomic Resolution EELS
Paul Cueva, Robert Hovden, Julia A. Mundy +2
The high beam current and sub-angstrom resolution of aberration-corrected scanning transmission electron microscopes has enabled electron energy loss spectroscopic (EELS) mapping w…
Atomic-resolution spectroscopic imaging of ensembles of nanocatalyst particles across the life of a fuel cell
Huolin L. Xin, Julia A. Mundy, Zhongyi Liu +8
The thousandfold increase in data-collection speed enabled by aberration-corrected optics allows us to overcome an electron microscopy paradox - how to obtain atomic-resolution che…
Caged clusters in AlIr: structural transition and insulating phase
Marek Mihalkovič, C. L. Henley
Using pair potentials fitted to an ab--initio database, combined with replica--exchange simulated annealing, we show the complex, quasicrystal-related AlIr compound cont…
RbFe2+Fe3+F6: Synthesis, Structure, and Characterization of a New Charge-Ordered Magnetically Frustrated Pyrochlore-Related Mixed-Metal Fluoride
Sun Woo Kim, Sang-Hwan Kim, P. Shiv Halasyamani +5
A new charge-ordered magnetically frustrated mixed-metal fluoride with a pyrochlore-related structure has been synthesized and characterized. The material, RbFe2F6 (RbFe2+Fe3+F6) w…
Defect evolution and interplay in n-type InN
Christian Rauch, Filip Tuomisto, Arantxa Vilalta-Clemente +5
The nature and interplay of intrinsic point and extended defects in n-type Si-doped InN epilayers with free carrier concentrations up to 6.6x10E20cm-3 are studied using positron an…
Magnetic switching by spin torque from the spin Hall effect
Luqiao Liu, O. J. Lee, T. J. Gudmundsen +2
The spin Hall effect (SHE) generates spin currents within nonmagnetic materials. Previously, studies of the SHE have been motivated primarily to understand its fundamental origin a…
Determining On-Axis Crystal Thickness with Quantitative Position-Averaged Incoherent Bright-Field Signal in an Aberration-corrected STEM
Huolin L. Xin, Ye Zhu, David A. Muller
An accurate determination of specimen thickness is essential for quantitative analytical electron microscopy. Here we demonstrate that a position-averaged incoherent bright-field s…
Interface control of emergent ferroic order in Ruddlesden-Popper SrTiO
Turan Birol, Nicole A. Benedek, Craig J. Fennie
We have discovered from first-principles an unusual polar state in the low n SrTiO Ruddlesden-Popper (RP) layered perovskites in which ferroelectricity is near…
Empirical oscillating potentials for alloys from ab-initio fits and the prediction of quasicrystal-related structures in the Al-Cu-Sc system
M. Mihalkovic, C. L. Henley
By fitting to a database of ab-initio forces and energies, we can extract pair potentials for alloys, with a simple six-parameter analytic form including Friedel oscillations, whic…
Band Gap and Edge Engineering via Ferroic Distortion and Anisotropic Strain: The Case of SrTiO
Robert F. Berger, Craig J. Fennie, Jeffrey B. Neaton
The effects of ferroic distortion and biaxial strain on the band gap and band edges of SrTiO (STO) are calculated using density functional theory and many-body perturbation t…
Polar octahedral rotations: a path to new multifunctional materials
Nicole A. Benedek, Andrew T. Mulder, Craig J. Fennie
Perovskite ABO oxides display an amazing variety of phenomena that can be altered by subtle changes in the chemistry and internal structure, making them a favorite class of mat…
Octahedral rotation-induced ferroelectricity in cation ordered perovskites
James M. Rondinelli, Craig J. Fennie
Increasing demands for electric field-tunable electric, magnetic, and orbital (EMO) materials has renewed interests in ferroelectricity and its coupling to EMO properties in comple…
A joint time-dependent density-functional theory for excited states of electronic systems in solution
Johannes Lischner, T. A. Arias
We present a novel joint time-dependent density-functional theory for the description of solute-solvent systems in time-dependent external potentials. Starting with the exact quant…
Computationally-Driven Experimental Discovery of the CeIrIn Compound
D. J. Fredeman, P. H. Tobash, M. A. Torrez +6
We present a combined experimental and computational methodology for the discovery of new materials. Density functional theory (DFT) formation energy calculations allow us to predi…
The role of magnetic anisotropy in spin filter junctions
R. V. Chopdekar, B. B. Nelson-Cheeseman, M. Liberati +2
We have fabricated oxide based spin filter junctions in which we demonstrate that magnetic anisotropy can be used to tune the transport behavior of spin filter junctions. Until rec…
Quantitative modeling of \textit{in situ} x-ray reflectivity during organic molecule thin film growth
Arthur R. Woll, Tushar V. Desai, James R. Engstrom
Synchrotron-based x-ray reflectivity is increasingly employed as an \textit{in situ} probe of surface morphology during thin film growth, but complete interpretation of the results…
