Abstract :
In this research, SrSe/ZrSe super-lattice was synthesized using an electrochemical deposition technique. The XRD pattern reveals a polycrystalline cubic structure with a diffraction angle at 2 thetas 11.93o, 13.97o, 20.87o, and 27.71o. Introducing ZrSe increased the peak intensity, signifying improved film crystallinity. Time significantly affected the electrical parameters and thickness of SrSe/ZrSe super-lattice. The film s absorbance decreases as its wavelength increases. The film s transmittance increases with wavelength. The SrSe/ZrSe synthesized at normal time had a bandgap energy of 2.50 eV. As the deposition time increased, the bandgap energy decreased to 2.39 - 2.22 eV.
