Determination of Thermal Diffusive Properties of Silver and Copper

August 26, 2021 Chemical and Material Science 0

Copper is used extensively in electrical power transmission, plumbing, cookware, and other applications because it is the most abundant and least expensive of the noble and precious metals, such as copper (Cu) island on silver (Ag) with good electrical and thermal conductivity. Silver’s chemical stability and strong electrical conductivity are two of its most essential characteristics. Bulk Ag has supplanted less expensive non-noble metals like aluminium as a common material for high-quality reflectors of electromagnetic radiation in the visual range. Diffusion is carried out at three different temperatures: 300, 500, and 700 K. For Ag, the lattice parameter was estimated and compared to experimental results. It has been discovered that as the temperature rises, so does the rate of diffusion. 5.24 10112/s is the diffusion prefactor. The effective energy barrier and diffusion coefficient have Arrhenius plot offers the effective energy barrier value of 143.56 meV and diffusion prefactor value of 5.24 10112/s for 10-atom island, according to previous experimental and theoretical studies. In terms of the theoretical and practical work done so far, the diffusion coefficient and effective energy barrier values are in the same range as for the other islands. Near the island, cracks and dislocations have been discovered at 300 K. These conclusions, on the other hand, are consistent with recent discoveries based on ab-initio electron structure calculations.
