Designer magneto-optics with plasmonic magnetic nanostructures
(2016-12-09)
La nanotecnología es un campo emergente y relativamente nuevo de la investigación, que ha ganado un gran interés en los últimos años. El término ¿nano¿ es un prefijo derivado de la palabra griega ¿¿¿¿¿ (nános) y significa ...
Modelling thermo-electric transport and excited states in low dimensional systems
(2016-06-17)
The interaction of radiation with matter at the nanoscale has an inexhaustible range of applicationsin electronics, biotechnology and medicine. At the nanoscale, the length scale wherethe classical and quantum worlds meet, ...

El trabajo de esta tesis doctoral comprende el estudio teórico de diferentes propiedades electrónicas de nanopartículas metálicas.Se utilizan técnicas de cálculo dentro del marco de la teoría del funcional de la densidad ...
Spin injection in two-dimensional layered materials and local magnetoresistance side-effects
(2016-04-08)
El objetivo principal de esta tesis ha sido estudiar la inyección de espines en el disulfuro de molibdeno (MoS2). Este material es interesante por varias razones: por un lado, es un semiconductor (SC), y por lo tanto ...
Strain-induced effects in the electronic and spin properties of a monolayer of ferromagnetic GdAg 2
(Royal Society of Chemistry, 2016)
We report on the structural, electronic and magnetic properties of a monolayer of GdAg2, forming a moire pattern on Ag(111). Combining scanning tunneling microscopy and ab initio spin-polarized calculations, we show that ...
Analysis and control of transient spectra using time-dependent density functional theory.
(2016-01-29)
Attosecond-transient absorption spectroscopy and attosecond time-resolved photoelectronspectroscopy based on pump-probe setups have recently become possibledue to the availability of ultra-fast pulsed laser sources. These ...
Network dynamics in nanofilled polymers
(Nature Publishing, 2016-04-25)
It is well accepted that adding nanoparticles (NPs) to polymer melts can result in significant property improvements. Here we focus on the causes of mechanical reinforcement and present rheological measurements on favourably ...
Spin-texture inversion in the giant Rashba semiconductor BiTeI
(Nature Publishing, 2016-05)
Semiconductors with strong spin-orbit interaction as the underlying mechanism for the generation of spin-polarized electrons are showing potential for applications in spintronic devices. Unveiling the full spin texture in ...
Quantifying electronic band interactions in van der Waals materials using angle-resolved reflected-electron spectroscopy
(Nature Publishing, 2016-11-29)
High electron mobility is one of graphene's key properties, exploited for applications and fundamental research alike. Highest mobility values are found in heterostructures of graphene and hexagonal boron nitride, which ...
Quantum plasmonics: from jellium models to ab initio calculations
(Walter de Gruyter, 2016-08)
Light-matter interaction in plasmonic nanostructures is often treated within the realm of classical optics. However, recent experimental findings show the need to go beyond the classical models to explain and predict the ...
