An electrostatically-assisted strategy for fabrication of thin film composite capacitors with controllable dielectric constant (k) has been developed. The capacitor is composed of metal–dielectric core/shell na. ••We fabricated thin film capacitor using electrostatic-assisted dip-c. Capacitors are integral components of electronic devices, for efficient power management and switching, and new dielectric materials are sought after for keeping up with. 2.1. Preparation of Ag@SiO2 core/shell nanoparticlesThe synthesis of Ag@SiO2 core–shell particles was based on previously reported procedure. B. 3.1. Thin film composite capacitor fabricated with Ag@SiO2 core/shell nanoparticlesAs we discussed previously, although the traditional metal–. In conclusion, novel thin film composite dielectrics capacitors were fabricated by electrostatically assisted adsorption process with Ag@SiO2 core/shell NPs multilayer films a.
