The effect of scattering of phonons, size and grain boundary on electrical properties for (Co and Ni) nano metals

Abstract In this study of the electrical properties of metals (Nickel, Cobalt), we utilize the Fuchs-Sondheier model to analyse the surface scattering of electrons, commonly known as the surface scattering coefficient (p). Our findings reveal the impact of thickness on electrical resistivity for these metals. the Mayadas-Shatzkes model show speaks to all sorts of scattering that influence grain boundaries and known as grain boundary reflection coefficient (R), two of the foremost critical essential components that utilized in assessing measure impact agreeing to theoretical considers. influences electrical resistivity for Cobalt and Nickel. where the electrical characteristics of metal shift depending on the substance’s concentration (impurities, point defects and vacancies). The comes about at that point illustrated that the electrical resistivity at all temperatures increases with diminishing thickness, which shows that Cobalt and Nickel has surface scattering coefficient p (Co) =0.64, p (Ni) =0.543, Cobalt has R=0.0434 and Nickel R=0.011 as the grain boundary reflection coefficient.
