A first principles study of thiol-capped Au nanoparticles: structural, electronic, and magnetic properties as a function of thiol coverage.
We have studied the stability of thiolated Au38 nanoparticles (NPs) via density functional theory based calculations varying the coverage from 0 up to 32 molecules. Three different initial core arrangements were considered for the cluster, spherical, tubular, and bi-icosahedral, while thiol groups were attached to the cluster via the sulfur atom either as single molecules or forming more comple...
متن کاملSurface plasmon resonance and magnetism of thiol-capped gold nanoparticles.
Surface plasmon resonance measurements and magnetic characterization studies have been carried out for two types of thiol-capped gold nanoparticles (NPs) with similar diameters between 2.0 and 2.5 nm and different organic molecules linked to the sulfur atom: dodecanethiol and tiopronin. In addition, Au NPs capped with tetraoctyl ammonium bromide have also been included in the investigation sinc...
متن کاملPermanent Magnetism in Thiol Capped Nanoparticles, Gold and ZnO
In spite of the diamagnetic behavior exhibited by bulk ZnO and Au, a ferromagnetic-like behavior is induced in nanoparticles of both systems by appropriate surface functionalization. By capping with thiol derivatized molecules, magnetic hysteresis is observed even at room temperature, whereas the magnetization has a very little temperature dependence. Capping induces an alteration of their elec...
متن کاملSuspended hybrid films assembled from thiol-capped gold nanoparticles
In this work, we explored the formation processes of suspended hybrid thin films of thiol-capped Au nanoparticles (AuNPs) inside metal oxide tubular structures. We found that a balance between in-film interactions of the AuNPs and boundary interactions with metal oxides is a key in making these special organic-inorganic thin films. The hybrid films process many processing advantages and flexibi...
متن کاملMagnetic properties of Au/Co/Ni80Fe20/Co/Au layered structures
The influence of an ultrathin cobalt layer at permalloy/gold interfaces in Au/Ni80Fe20/Au sandwiches and spin-valve (Ni80Fe20/Au/Co/Au)N multilayers on their magnetic and magnetotransport properties is investigated. We show that an effective magnetic anisotropy of Co/Ni80Fe20/Co hybrid structures sandwiched between Au layers can be easily varied by the thickness adjustment of Co and Ni80Fe20 la...
