Abstract: Thin films of Cd 0.7 Fe 2.3 O 4 were deposited by spray pyrolysis on glass, quartz, and n-type silicon substrates, and the effect of annealing temperature on their structural, optical, and electrical properties was investigated. XRD results confirm the formation of a spinel structure after annealing, accompanied by improved crystallinity. Optical measurements reveal strong absorption in the UV–visible range, with a band gap varying from 3.14 to 3.85 eV. FTIR analysis confirms the presence of Cd–O and Fe–O bonds. Electrical characterization of the Cd 0.7 Fe 2.3 O 4 /n-Si heterostructure shows rectifying behavior, with the ideality factor decreasing from 6 to 1 as temperature increases, indicating improved carrier transport. These results demonstrate the potential of this material for electronic and optoelectronic applications.
