Abstract
Barium titanate (BaTiO3) has been extensively used as a compound due to its potential for optoelectronics and electronic applications. The density functional theory (DFT) calculations as well as chemically prepared thin films were used to investigate the effect of the alkaline earth metal Sr on the electronic, thermoelectric, structural, morphological, and optical properties of the BaTiO3 host matrix. It was found in band structure analysis that the bandgap nature changed from indirect to direct bandgap upon incorporation of the Sr atom into the BaTiO3 host lattice. Thermoelectric characteristics showed notable changes in response to temperature and doping. The investigation demonstrated that optimized electrical conductivity, reduced thermal conductivity, and an enhanced Seebeck coefficient were achieved with a precise (5.55 %) Sr content. XRD analysis revealed the cubic phase of the prepared thin films. Morphological investigation showed the evolution of grain with the increase in dopant contents. The theoretical and experimentally measured optical characteristics also revealed that Sr doping improved the material’s refractive index, conductivity, and absorption coefficient in the visible and ultraviolet energy ranges. Significant enhancements in electronic, thermoelectric, and optical properties suggest that doped BaTiO3 could be considered a potential applicant for optoelectronic as well as thermoelectric applications.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
