The Effect of Annealing Temperature on Spin-Coated Zn-doped NiO film for humidity sensing applications / N.F.Q. Fahmi … [et al.]

Zinc (Zn)-doped nickel oxide (NiO) thin films were fabricated using spin coating technique for humidity sensing applications. Nickel acetate tetrahydrate was used as a precursor material and zinc acetate was used as the dopant source. The films were annealed at various annealing temperatures of 400...
