Quasi-zero lattice mismatch and band alignment of BaTiO3 on epitaxial (110)Ge
(American Institute of Physics, 2013-07-14)
Growth, structural, and band alignment properties of pulsed laser deposited amorphous BaTiO3 on epitaxial molecular beam epitaxy grown (110) Ge layer, as well as their utilization in low power transistor are reported. ...
Lead-free and lead-based ABO(3) perovskite relaxors with mixed-valence A-site and B-site disorder: comparative neutron scattering structural study of (Na1/2Bi1/2) TiO3 and Pb(Mg1/3Nb2/3)O-3
(American Physical Society, 2013-11-01)
We report the results of neutron elastic-scattering measurements made between -250 degrees C and 620 degrees C on the lead-free relaxor (Na1/2Bi1/2)TiO3 (NBT). Strong, anisotropic, elastic diffuse scattering intensity ...
X-ray diffraction study of the pressure-induced bcc-to-hcp phase transition in the highly magnetostrictive Fe0.81Ga0.19 alloy
(American Physical Society, 2013-11-07)
High-pressure x-ray diffraction measurements were performed at room temperature on single crystals of the highly magnetostrictive alloy Fe0.81Ga0.19 (galfenol). This alloy has a bcc crystal structure at ambient pressure ...
Efficient methods for computing observation impact in 4D-Var data assimilation
A systematic review of studies on forecasting the dynamics of influenza outbreaks
Forecasting the dynamics of influenza outbreaks could be useful for decision-making regarding the allocation of public health resources. Reliable forecasts could also aid in the selection and implementation of interventions ...
Mechanical loss and magnetoelectric response in magnetostrictive/interdigitated-electrode/piezoelectric laminated resonators
(American Institute of Physics, 2013-03-28)
The mechanical quality factor and the resonant magnetoelectric (ME) response of multi-push-pull mode Metglas/interdigitated (ID)-electrode/Pb(Zr,Ti)O-3 (PZT) ME resonators have been studied as a function of ID-electrode ...
Structural and band alignment properties of Al2O3 on epitaxial Ge grown on (100), (110), and (111)A GaAs substrates by molecular beam epitaxy
(American Institute of Physics, 2013-04-07)
Structural and band alignment properties of atomic layer Al2O3 oxide film deposited on crystallographically oriented epitaxial Ge grown in-situ on (100), (110), and (111)A GaAs substrates using two separate molecular beam ...
Kinetics and thermodynamics of the ferroelectric transitions in PbMg1/3Nb2/3O3 and PbMg1/3Nb2/3O3-12% PbTiO3 crystals
(American Institute of Physics, 2013-05-14)
The two-step freezing and melting of the field-induced ferroelectric order in PbMg1/3Nb2/3O3 (PMN) and (PbMg1/3Nb2/3O3)(0.88)(PbTiO3)(0.12) (PMN-PT) is investigated. In PMN-PT, direct microscopic images show that both steps ...
Stress reconfigurable tunable magnetoelectric resonators as magnetic sensors
(AIP Publishing, 2013-01-01)
We report a magnetoelastic effect in doubly clamped ferromagnetic magnetostrictive Metglas resonators with electrically and magnetically reconfigurable frequency response. The field-induced resonance frequency shift is due ...
Giant self-biased magnetoelectric coupling in co-fired textured layered composites
(AIP Publishing, 2013-02-01)
Co-fired magnetostrictive/piezoelectric/magnetostrictive laminate structure with silver inner electrode was synthesized and characterized. We demonstrate integration of textured piezoelectric microstructure with the ...
