Impact of Nickel Concentration on Structural, Morphological and Optical Properties of Jet Nebulizer Spray pyrolysis Coated Ni-MoO3 Thin Films: Evaluation of n-Ni-MoO3/p-Si Junction Didoes

Abstract

Monoclinic structured MoO₃ thin films were prepared on a glass substrate. The Ni doped materials to add the MoO₃ in different concentrations (1%, 3%, 5%) at Wt% with MoO₃ precursor and synthesis was done using the spray pyrolysis method. X-ray diffraction revealed the incorporation of Ni in the MoO₃ Monoclinic structure. FE-SEM images showed more dispersive and rod shapes than Ni-doped MoO₃ and pure MoO₃ respectively. The ideality factor, barrier height, and saturation current were measured for two samples pure MoO₃ and Ni-doped MoO₃ at 5% doping level. The ideality factor was calculated using electrical measurements, while the barrier height and saturation current were determined through analysis of the current-voltage (I-V) characteristics.
