By studies in condensed matter physics, as a particle decreases, unicity’s become peculiar, and may even define new properties in their nanostructure, be they electrical, chemical, among others1. Based on the study of the formation of nanoparticles (NP’s) of iron oxides (Fe2O3), which present very interesting electronic properties, such as chemical changes in the atomic structures on external medium interference2. Therefore, (Fe2O3) is promising for nanotechnology that motivates new applications in the engineering, of equal nature are other nanoparticles, being Pd (Pd), Platinum (Pt), Copper (Cu). The latter as excellent conductor of electricity and therefore is very much employed in the manufacture of wires and electrical appliancesin macro scale. Directed by energy storage applications, it is analyzed the possible interactions of metallic nanostructures on the quantity of load carriers, using potential differences on a set of nanostructured plates in parallel3. In this way a supercapacitor can be forged, with an electric field generated between the areas of the plates by a minimum distance and isolated by a high dielectric stiffness4. Suitable for qualitative and quantitative results on device capacitance, loading and unloading time, efficiency in applications with the use of nanostructured thin films.
