Electrochemical Strain Microscopy with Blocking Electrodes: The Role of Electromigration and Diffusion
A. N. Morozovska, E. A. Eliseev, S. V. Kalinin
Electrochemical strains are a ubiquitous feature of solid state ionic devices ranging from ion batteries and fuel cells to electroresistive and memristive memories. Recently, we pr…
Frequency Dependent Dynamical Electromechanical Response of Mixed Ionic-Electronic Conductors
A. N. Morozovska, E. A. Eliseev, S. L. Bravina +4
Frequency dependent dynamic electromechanical response of the mixed ionic-electronic conductor film to a periodic electric bias is analyzed for different electronic and ionic bound…
The Role of Polytetrahedral Structures in the Elongation and Rupture of Gold Nanowires
Christopher R. Iacovella, William R. French, Brandon G. Cook +2
We report comprehensive high-accuracy molecular dynamics simulations using the ReaxFF forcefield to explore the structural changes that occur as Au nanowires are elongated, establi…
The Influence of Molecular Adsorption on Elongating Gold Nanowires
William R. French, Christopher R. Iacovella, Peter T. Cummings
Using molecular dynamics simulations, we study the impact of physisorbing adsorbates on the structural and mechanical evolution of gold nanowires (AuNWs) undergoing elongation. We…
Domain wall conduction in multiaxial ferroelectrics
Eugene A. Eliseev, Anna N. Morozovska, George S. Svechnikov +2
The conductance of domain wall structures consisting of either stripes or cylindrical domains in multi-axial ferroelectric-semiconductors is analyzed. The effects of the domain siz…
Temperature Driven Structural Phase Transition in Tetragonal-Like BiFeO3
Wolter Siemons, Michael D. Biegalski, Joong Hee Nam +1
Highly-strained BiFeO3 exhibits a "tetragonal-like, monoclinic" crystal structure found only in epitaxial films (with an out-of-plane lattice parameter exceeding the in-plane value…
Antiferromagnetic transitions in `T-like' BiFeO3
G. J. MacDougall, H. M. Christen, W. Siemons +5
Recent studies have reported the existence of an epitaxially-stabilized tetragonal-like ('T-like') monoclinic phase in BiFeO3 thin-films with high levels of compressive strain. Whi…
Nanoscale Electromechanics of Paraelectric Materials with Mobile Charges: Size effects and Nonlinearity of Electromechanical Response of SrTiO3 Films
A. N. Morozovska, E. A. Eliseev, G. S. Svechnikov +1
Nanoscale enables a broad range of electromechanical coupling mechanisms that are forbidden or negligible in the materials. We conduct a theoretical study of the electromechanical…
Simple Impurity Embedded in a Spherical Jellium: Approximations of Density Functional Theory compared to Quantum Monte Carlo Benchmarks
Michal Bajdich, Paul R. C. Kent, Jeongnim Kim +1
We study the electronic structure of a spherical jellium in the presence of a central Gaussian impurity. We test how well the resulting inhomogeneity effects beyond spherical jelli…
