Its application is based on electro-optical properties, one of which is the infrared thermal switch. This paper aims to determine the bandgap energy (Eg) of a 0.3BaTiO3 – 0.7BaZr0.5Ti0.5O3 thin film. The 0.3BaTiO3 – 0.7BaZr0.5Ti0.5O3 thin film is a semiconductor material with the valence band and conduction band separated by an energy bandgap (Eg). Thin films of 0.3BaTiO3 – 0.7BaZr0.5Ti0.5O3 were grown on FTO substrates using the sol-gel method. The films of 0.3BaTiO3 – 0.7BaZr0.5Ti0.5O3 were annealed at different temperatures of 700°C, 750°C and 800°C within 1 hour. Characterization was carried out using Ultra Violet Visible (UV-Vis) spectroscopy to determine Eg using the Diffusion Reflectance Spectroscopy (DRS) method. The DRS method was found to be better for solid materials considering the scattering component. The UV-Vis characterization re...

Therefore, this study aims to explore Barium Strontium Titanate (BST) as the basis in the making of dynamic random access memory (DRAM). This DRAM technology produces small cells that have faster operations, lower energy, longer data storage period, and are found to havemade up of Barium Strontium Titanate nanoparticles (Ba0.4Sr0.6TiO3; BST). BST applications in the form of capacitors can be used as gas sensors, temperature sensors, microwave phase shifters, tunable filters, oscillators, infrared sensors, etc.The main component of BST was showed by the sol-gel method, and the device structure constituted of Si/SiO2/RuO2/TiO2 /Ba0.4Sr0.6TiO3/Al. All the samples were annealed at 400, 450, 500, 550, 600, 650 and 700 ℃ for 60 min. The sample was annealed to see the crystalline structure of the sample.The sol gel method was chosen in the process of making thin films of Ba0.4Sr0.6TiO3 (BS...

Ferroelectric product of Ba0,7Sr0,3TiO3 was characterized by Scanning Electron Microscopy (SEM). Sizes of ferroelectric particle increased with sintering temperatures, as follow 1,67µm, 2,27µm, and 2,38µm for samples with high temperature of 600oC, 700oC and 800oC. Respectively then the density of particle decreased with temperature i.e 5,03x10-4 %, 4,40x10-4 %, and 1,52x10 -4 %.

Variable coating rates do not influence the microstructure of the films. All films are polycrystalline and single phase, as was found from X-ray diffraction analysis. Changing the spin rates also does not influence the grain sizes of the films. All films have nanometer particle size ranging from 37.2 nm to 30.7 nm. However, roughness and thickness of the film depend on the spin coating rates. The highest spin rates produce the thinnest film with the roughest surface, while the lowest spin rate produced the thickest films with the smoothest surface.
