IRAQI JOURNAL OF APPLIED PHYSICS Vol. 22, No. 3, July-September 2026, pp. 333-339 Studying Effect of Frequency on Nisreen A. Fejer 1,2* Capacitance–Resistance of Mohammed T. Hussein 3,4 Asmaa H. Mohammed 2 Al/ITO/Al Humidity Sensor Prepared by Pulsed-Laser Deposition 1 College of Women Science, University of Baghdad, Indium tin oxide (ITO) nanostructured films were deposited onto glass substrates Baghdad, IRAQ using pulsed-laser deposition. The structure, shape, and optical properties of the 2 College of Science, deposited films were characterized. The ITO films were found to be polycrystalline University of Al Nahrain, with preferred at (222) crystal orientation (2θ=30.65°), and average crystallite size of Baghdad, IRAQ about 23.22 nm when annealed at 200 °C for 60 minutes. The films exhibited an 3 College of Science, optical band gap around 3.4 eV due to the nanostructure formation and deposition University of Baghdad, method. The films showed uniform morphology with minimum surface
