| Abstract |
Analog computing from recycling principle for next circular economy scenario has been studied with an iron oxide-coupled graphite/Fe-Si steel structure which was built using recycled waste materials, such as lead pencil and 3% Si steel (Fe-Si steel) foils. Proximity phenomena, such as disordered structure of iron oxide and magnetostriction-induced conduction, inside graphite lattice resulted in functional properties to advance analog architectures. Thermal oxidation was the synthesis route to produce iron oxide as coating film on Fe-Si steel foil, whose structure properties were validated by Raman spectroscopy where phase formation of hematite, alpha-Fe2O3, resulted as iron oxide thin-film. Three graphite layers with different compositions were also analyzed by Raman spectroscopy and used for studying electrical conduction in Fe-Si steel/alpha-Fe2O3/graphite structure from current-voltage plots at room temperature. |
