Broadband saturable absorption and exciton-exciton annihilation in MoSe2 composite thin films
(2019)
Polyvinyl alcohol (PVA) was utilized as a matrix to host two-dimensional (2D)
liquid-phase-exfoliated MoSe2 nanosheets. These 2D MoSe2/PVA composite thin films were
experimentally proven to be preferable for efficient ...
Dynamical exchange interaction from time-dependent spin density functional theory
(2013)
We report on ab initio time-dependent spin-dynamics simulations for a two-center magnetic molecular complex within the framework of the time-dependent noncollinear spin-density functional theory. In particular, we discuss ...
Hydrogen bonding as the origin of the switching behavior in dithiolated phenylene-vinylene oligomers
(2013)
We investigate theoretically the switching behavior of a dithiolated phenylene-vinylene oligomer sandwiched between Au(111) electrodes using self-interaction corrected density-functional theory combined with the nonequilibrium ...

Strain-induced modulation of magnetic interactions in graphene
(2012)
The ease with which the physical properties of graphene can be tuned suggests a wide range of possible
applications. Recently, strain engineering of these properties has been of particular interest. Possible spintronic

Nonequilibrium Green's function study of Pd4-cluster-functionalized carbon nanotubes as hydrogen sensors
(2009)
Pd-cluster-functionalized carbon nanotubes
CNTs
have been shown experimentally to be effective hydro-
gen sensors. Semiconducting CNTs exhibit much higher sensitivity than ensemble
mixed
ones. Using the
nonequilibrium ...
Prediction of large bias-dependent magnetoresistance in al l-oxide magnetic tunnel junctions with a ferroelectric barrier
(2011)
All-oxide magnetic tunnel junctions (MTJs) incorporating functional materials as insulating barriers have the potential of becoming the founding technology for novel multifunctional devices. We investigate, by first-principles ...
Optical Anisotropy of SrTiO3(110) for Different Surface Terminations
(2017)
In this work we investigate the SrTiO3(110) surface by reflectance anisotropy spectroscopy (RAS) at varying preparation steps including ex situ wet etching, high temperature oxygen annealing, as well as in situ vacuum ...
Antiferromagnetic single-layer spin-orbit torque oscillators
(2019)
We show how a charge current through a single antiferromagnetic layer can excite and control self-oscillations. Sustained oscillations with tunable amplitudes and frequencies are possible in a variety of geometries using ...
Spin-dependent electronic structure of the Co/Al(OP)3 interface
(2013)
We have studied the spin-dependent electronic properties of the interface formed between epitaxial Co thin films deposited on Cu(001) and the experimental molecule tris-(9-oxidophenalenone)-aluminum(III) (Al(OP)3), created ...
