    摘要: Process for the synthesis of nanoparticles comprising oxidation sensitive metals, in particular copper comprising the following steps: Preparation and nucleation of citrate-capped Metal-hydroxide nanoparticles, reduction of the intermediate citrate-capped Metal-hydroxide nanoparticles to Metal 0 by reduction via NaBH 4 Cu 0 nanoparticles with narrow size distribution are obtained by NaBH 4 Li-induced reduction of CUCI 2 2H 2 O in diethylene glycol. The course of the reaction essentially involves an intermediate formation of Cu(OH) 2 nanoparticles as well as the presence of citrate to control the nucleation of almost monodisperse and non-agglomerated Cu 0 nanoparticles. The citrate-capped Cu 0 nanoparticles of the invention are surprisingly stable against air oxidation. Via simple solvent evaporation, porous Cu 0 thin-films are prepared on glass substrates that exhibit bulk-like sheet resistances of 0.23 - 0.42 Ω ϛ after vacuum sintering at 250 °C (bulk-Cu sheet under similar conditions with: 0.3 Ω ϛ ). With these features the as-prepared, citrate-capped Cu 0 nanoparticles become highly relevant to electronic devices in particular thin-film electronics, thin-film sensors and high-power batteries.

    摘要: The invention relates to a resonant diode having a ferromagnetic (FM) tunnel contact for generating an electric current, the amplitude of which is determined by the polarization state of the absorbed light. The invention is essentially characterized by the presence of a stack of semi-conductor layers (B1, W, B2) thus defining a carrier confinement area. The operation principle comprises generating polarized carriers, electron-hole pairs in dual-barrier quantum semi-conductor wells or boxes by the resonant absorption of a light wave having circular or elliptic polarization. The invention can be used as a basic element or in the form of a two-dimensional array as a magnetic memory element, a light polarization detector, or a magnetic field sensor.
