Measurement of Ultrafast Carrier Dynamics in Epitaxial Graphene
Jahan M. Dawlaty, Shriram Shivaraman, Mvs Chandrashekhar +2
Using ultrafast optical pump-probe spectroscopy, we have measured carrier relaxation times in epitaxial graphene layers grown on SiC wafers. We find two distinct time scales associ…
Magnetic resonance in iron oxide nanoparticles: quantum features and effect of size
Maxim M. Noginov, N. Noginova, O. Amponsah +3
In order to better understand the transition from quantum to classical behavior in spin system, electron magnetic resonance (EMR) is studied in suspensions of superparamagnetic mag…
Time-Domain Studies of Very-Large-Angle Magnetization Dynamics Excited by Spin Transfer Torques
I. N. Krivorotov, N. C. Emley, R. A. Buhrman +1
We describe time-domain measurements which provide new information about the large-angle nonlinear dynamics of nanomagnets excited by spin-transfer torque from a spin-polarized cur…
Fractal dimension and size scaling of domains in thin films of multiferroic BiFeO3
G. Catalan, H. Bea, S. Fusil +4
We have analyzed the morphology of ferroelectric domains in very thin films of multiferroic BiFeO3. Unlike the more common stripe domains observed in thicker films BiFeO3 or in oth…
Photocurrent Imaging of p-n Junctions and Local Defects in Ambipolar Carbon Nanotube Transistors
Y. H. Ahn, Wei Tsen, Bio Kim +2
We use scanning photocurrent microscopy (SPCM) to investigate the properties of internal p-n junctions as well as local defects in ambipolar carbon nanotube (CNT) transistors. Our…
Atomic-scale structure of the SrTiO3(001)-c(6x2) reconstruction: Experiments and first-principles calculations
C. H. Lanier, A. van de Walle, N. Erdman +7
The c(6x2) is a reconstruction of the SrTiO3(001) surface that is formed between 1050-1100oC in oxidizing annealing conditions. This work proposes a model for the atomic structure…
Grain boundary energies and cohesive strength as a function of geometry
Valerie R. Coffman, James P. Sethna
Cohesive laws are stress-strain curves used in finite element calculations to describe the debonding of interfaces such as grain boundaries. It would be convenient to describe grai…
Classical potential describes martensitic phase transformations between the , and titanium phases
R. G. Hennig, T. J. Lenosky, D. R. Trinkle +2
A description of the martensitic transformations between the , and phases of titanium that includes nucleation and growth requires an accurate classical potential. Optim…
Spin-Torque Ferromagnetic Resonance Measurements of Damping in Nanomagnets
G. D. Fuchs, J. C. Sankey, V. S. Pribiag +8
We measure the magnetic damping parameter a in thin film CoFeB and permalloy (Py) nanomagnets at room temperature using ferromagnetic resonance driven by microwave frequency spin-t…
Nonlinear response theories and effective pair potentials
Simon Gravel, N. W. Ashcroft
We present a general method based on nonlinear response theory to obtain effective interactions between ions in an electron gas which can also be applied to other systems where an…
