Abstract
Nanodielectric is an emerging field with applications in capacitors, gate dielectrics, and as energy storage-alternates to Li-Ion batteries such as in communication devices. Nanodielectrics are related to the dielectric phenomenon of nanoscale materials having morphology comprised of nanoparticles, nanowires, nanotubes and nano sheets. Extensive interest is being directed toward research in energy storage solutions for both discrete and embedded capacitors. Since the dielectric behavior can be tailored by simply controlling the type and the amount of the nano-fillers in the host polymer, there is an opportunity to exploit nanocomposites. This paper addresses materials and processes for energy storage in high k embedded capacitors using metal nanoparticles coated and uncoated with Sio(2) shells (M@Sio(2), where M = Au, and Ag,) and high K polymer matrices for stabilization. Specifically, we present the effective fabrication and the properties of Nanodielectrics produced with Ag and Au nanoparticles in a polymer (polyvinyl Pyrroldone, PVP) and Polystyrene (PS) matrices using core-shell nanostructure geometry.
