Highly filled particulate nanocomposite films consisting of metal nanoparticles in a
dielectric organic or ceramic matrix have unique functional properties with hosts of
applications [1]. The present talk demonstrates how vapor phase deposition techniques
can be employed for tailoring the nanostructure and the resulting properties. Vapor
phase deposition, inter alia, allows excellent control of the metallic filling factor and its
depth profile as well as the incorporation of alloy nanoparticles with well-defined
composition. We applied various methods such as sputtering, evaporation, and plasma
polymerization for the deposition of the matrix component, while the metallic
components were mostly sputter-deposited or evaporated. Moreover, a high-rate gas
aggregation cluster source was utilized to obtain independent control of filling factor
and size of the embedded nanoparticles. Examples include optical composites with
tuned particle surface plasmon resonances for plasmonic applications [2,3], magnetic
high frequency materials with cut-off frequencies well above 1 GHz [4], sensors [5] and
photoswitchable devices [6] that are based on the huge change in the electronic
properties near the percolation threshold, and biocompatible antibacterial coatings
with tailored release rate [7]. In addition to the particulate composites, it will be shown
how magnetoelectric layered composites consisting of magnetostrictive and
piezoelectric layers can be explored as low frequency magnetic field sensors with
sensitivities down to the pT range [8]. Finally, a new concept of a robust, fully
integrable, broad band magnetic field sensor based on the delta E effect will be
presented [9,10].
