Abstract
In recent years, the demand for efficient photodetectors within optoelectronic technology has driven the development of layered semiconductor materials at affordable prices. This study focuses on the fabrication of V2O5 thin films on glass and p-Si substrates with varying Sr content (0, 1, 3, and 5 wt%) using a cost-effective the perfume atomizer spray technique. The effect of Sr dopant on the morphological, structural, optical and electrical properties of V2O5 thin film was examined using standard characterization techniques such as XRD, AFM, UV–Vis, Hall measurement and I–V techniques. Doping V2O5 with low Sr content of 1, 3, and 5 wt% significantly impacts the lattice, as evidenced by changes in the orthorhombic structures. The resulting thin films exhibit bandgap values ranging from 2.50 to 2.64 eV. Hall Effect measurements at room temperature revealed n-type conduction for all samples. The study found that doping increases the carrier concentration, leading to a decrease in the resistivity of V2O5 by incorporating the dopant into the V2O5 matrix. Furthermore, Sr-doped V2O5 thin films were deposited on p-Si substrates to form p-n junctions. The voltage-current characteristics of the fabricated diodes were investigated under both dark and illuminated conditions.
