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 ...
A redox-active radical as an effective nanoelectronic component: stability and electrochemical tunnelling spectroscopy in ionic liquids
(Royal Society of Chemistry, 2016-10-28)
A redox-active persistent perchlorotriphenylmethyl (PTM) radical chemically linked to gold exhibits stable electrochemical activity in ionic liquids. Electrochemical tunnelling spectroscopy in this medium demonstrates that ...
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 ...
Elementary reactive processes of nitrogen and hydrogen on metal surfaces: A theoretical study
(2016-12-16)
We present a theoretical study of elementary reaction take place at solid surfaces. Calculations based on density functional theory (DFT) were performed to obtain the minimum energy structure of the Fe(111) surface as well ...
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 ...
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 ...
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 ...
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 ...
Phonon and electron excitations in abstraction processes from metallic surfaces
