Synergistic Enhancement of Electrical Conductivity and Thermoelectric Efficiency in ZnFe2O4─Fe2O3/Graphene Composites
This work demonstrates the successful improvement in the thermoelectric properties of the spinel ZnFe2O4 (ZFO) composite with multilayer graphene. Phase‐pure ZFO prepared using the sol–gel method was mixed with multilayer graphene, compacted, and sintered at 1200 °C for 5 h in an N2 atmosphere. A significant increment...
