Defect and structural imperfection effects on the electronic properties of BiTeI surfaces 

Fiedler, Sebastian; El-Kareh, Lydia; Eremeev, Sergey V.; Tereshchenko, Oleg E; Seibel, Christoph; Lutz, Peter; Kokh, Konstantin A; Tchoulkov Savkin, Evgueni Vladimirovich; Kuznetsova, Tatyana V; Grebennikov, Vladimir I; Bentmann, Hendrik; Bode, Matthias; Reinert, Friedrich (IOP Publishing, 2014-07-24)
The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology ...

Electronic properties of graphene grain boundaries 

Ayuela Fernández, Andrés; Jaskólski, Wlodzimierz; Santos Expósito, Hernán; Chico, Leonor (IOP Publishing, 2014-08-08)
Grain boundaries and defect lines in graphene are intensively studied for their novel electronic and magnetic properties. However, there is not a complete comprehension of the appearance of localized states along these ...

Acoustic plasmons in extrinsic free-standing graphene 

Pisarra, M.; Sindona, A.; Riccardi, P.; Silkin, Viatcheslav M.; Pitarke de la Torre, José María (IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...

An Embedded Stress Sensor for Concrete SHM Based on Amorphous Ferromagnetic Microwires 

Olivera, Jesús; González, Margarita; Fuente, José Vicente; Varga, Rastislav; Zhukov Egorova, Arkady Pavlovich; Anaya, José Javier (MDPI, 2014-11)
A new smart concrete aggregate design as a candidate for applications in structural health monitoring (SHM) of critical elements in civil infrastructure is proposed. The cement-based stress/strain sensor was developed by ...

Spin-helical Dirac states in graphene induced by polar-substrate surfaces with giant spin-orbit interaction: a new platform for spintronics 

Eremeev, Sergey V.; Nechaev, I. A.; Echenique Landiribar, Pedro Miguel; Tchoulkov Savkin, Evgueni Vladimirovich (Nature Publishing Group, 2014-11-04)
Spintronics, or spin electronics, is aimed at efficient control and manipulation of spin degrees of freedom in electron systems. To comply with demands of nowaday spintronics, the studies of electron systems hosting giant ...

Nonlinear magnetic vortex dynamics in a circular nanodot excited by spin-polarized current 

Gusliyenko, Kostyantyn; Sukhostavets, Oksana; Berkov, Dmitry V. (Springer International Publishing, 2014-08-08)
We investigate analytically and numerically nonlinear vortex spin torque oscillator dynamics in a circular magnetic nanodot induced by a spin-polarized current perpendicular to the dot plane. We use a generalized nonlinear ...

Germanene: a novel two-dimensional germanium allotrope akin to graphene and silicene 

Dávila, M. E.; Xian, Lede; Cahangirov, S.; Rubio Secades, Angel; Le Lay, G. (IOP Publishing, 2014-09-09)
We have grown an atom-thin, ordered, two-dimensional multi-phase film in situ through germanium molecular beam epitaxy using a gold (111) surface as a substrate. Its growth is similar to the formation of silicene layers ...

Giant diamagnetism of gold nanorods 

Hernando, A.; Ayuela Fernández, Andrés; Crespo, P.; Echenique Landiribar, Pedro Miguel (IOP Publishing, 2014-07-30)
The presence of giant diamagnetism in Au nanorods, NRs, is shown to be a possible consequence of field induced currents in the surface electrons. The distance, Delta , between quantum surface energy levels has been calculated ...

Hole-Phonon Relaxation and Photocatalytic Properties of Titanium Dioxide and Zinc Oxide: First-Principles Approach 

Zhukov, V. P.; Tyuterev, V. G.; Tchoulkov Savkin, Evgueni Vladimirovich; Echenique Landiribar, Pedro Miguel (Hindawi Publishing, 2014)
First-principles calculations for the temporal characteristics of hole-phonon relaxation in the valence band of titanium dioxide and zinc oxide have been performed. A first-principles method for the calculations of the ...

Microwave absorption properties of permalloy nanodots in the vortex and quasi-uniform magnetization states 

Gusliyenko, Kostyantyn; Kakazei, Gleb N.; Kobljanskyj, Yu V.; Melkov, G. A.; Novosad, V.; Slavin, A. N. (IOP Publishing, 2014-06-19)
When the in-plane bias magnetic field acting on a flat circular magnetic dot is smaller than the saturation field, there are two stable competing magnetization configurations of the dot: the vortex and the quasi-uniform ...
