Structural determination and electronic properties of 4d perovskite SrPdO3
Jiangang He, Cesare Franchini
The structure and ground state electronic structure of the recently synthesized SrPdO perovskite [A. Galal {\em et al.}, J. Power Sources, {\bf 195}, 3806 (2010)] have been stu…
Localized excited charge carriers generate ultrafast inhomogeneous strain in the multiferroic BiFeO
D. Schick, M. Herzog, H. Wen +7
We apply ultrafast X-ray diffraction with femtosecond temporal resolution to monitor the lattice dynamics in a thin film of multiferroic BiFeO after above-bandgap photoexcitati…
Prediction of high frequency intrinsic localized modes in Ni and Nb
M. Haas, V. Hizhnyakov, A. Shelkan +2
It is found that in some metals an intrinsic localized mode may exist with frequency above the top of the phonon spectrum. The necessary condition, requiring sufficiently high rati…
Transient absorption and photocurrent microscopy show hot electron supercollisions describe the rate-limiting relaxation step in graphene
Matt W. Graham, Su-Fei Shi, Zenghui Wang +3
Using transient absorption (TA) microscopy as a hot electron thermometer we show disorder-assisted acoustic-phonon supercollisions (SCs) best describes the rate-limiting relaxation…
Implicit solvation model for density-functional study of nanocrystal surfaces and reaction pathways
Kiran Mathew, Ravishankar Sundararaman, Kendra Letchworth-Weaver +2
Solid-liquid interfaces are at the heart of many modern-day technologies and provide a challenge to many materials simulation methods. A realistic first-principles computational st…
Epitaxial Growth of VO by Periodic Annealing
J. W. Tashman, J. H. Lee, H. Paik +9
We report the growth of ultrathin VO films on rutile TiO (001) substrates via reactive molecular-beam epitaxy. The films were formed by the cyclical deposition of amorp…
Thermally populated intrinsic localized modes in pure alkali halide crystals
A. J. Sievers, M. Sato, J. B. Page +1
The possibility of thermal excitation of intrinsic localized modes (ILMs) arising from anharmonicity in ionic perfect crystals is studied numerically for realistic model systems in…
Structural control of magnetic anisotropy in a strain driven multiferroic EuTiO3 thin film
X. Ke, T. Birol, R. Misra +5
Octahedral distortion plays a key role in engineering the physical properties of heterostructures composed of perovskite oxides. We observe a strong in-plane uniaxial magnetic anis…
Hetero-epitaxial EuO Interfaces Studied by Analytic Electron Microscopy
Julia A. Mundy, Daniel Hodash, Alexander Melville +6
With nearly complete spin polarization, the ferromagnetic semiconductor europium monoxide could enable next-generation spintronic devices by providing efficient ohmic spin injectio…
Control of Propagating Spin Waves via Spin Transfer Torque in a Metallic Bilayer Waveguide
Kyongmo An, Daniel R. Birt, Chi-Feng Pai +4
We investigate the effect of a direct current on propagating spin waves in a CoFeB/Ta bilayer structure. Using the micro-Brillouin light scattering technique, we observe that the s…
Why Are There So Few Perovskite Ferroelectrics?
Nicole A. Benedek, Craig J. Fennie
We use a combination of symmetry arguments and first-principles calculations to explore the connection between structural distortions and ferroelectricity in the perovskite family…
Graphene Metallization of High-Stress Silicon Nitride Resonators for Electrical Integration
Sunwoo Lee, Vivekananda P. Adiga, Robert A. Barton +7
High stress stoichiometric silicon nitride resonators, whose quality factors exceed one million, have shown promise for applications in sensing and signal processing. Yet, electric…
Origin of giant spin-lattice coupling and the suppression of ferroelectricity in EuTiO3 from first principles
Turan Birol, Craig J. Fennie
We elucidate the microscopic mechanism that causes a suppression of ferroelectricity and an enhancement of octahedral rotations in EuTiO3 from first principles. We find that the hy…
