Abstract

The structural, electronics, optical, and thermoelectric characteristics of BXO₃(X = P, As, Sb, and Bi) perovskites are investigated within the density functional theory (DFT) framework. The full potential linearized augmented plane wave method employs various exchange–correlation potential approximations to estimate the ground state’s physical properties. The ground state stability of BXO₃ perovskites was examined and all compounds have shown their cubic structure stability. The computed ground state structural parameters in the stability phase agree well with the available literature. Our results of optical properties indicated the potential use of BXO₃(X = P, As, Sb, and Bi) in visible and ultraviolet zones of optoelectronic devices. The studied perovskites have indirect bandgap energy except BSbO₃ has a direct bandgap. Notably, our findings show that except for BPO₃ the figure of merit (ZT) values approach unity within the temperature range of 100–800 K for BSbO₃ and BBiO₃. In contrast, for BAsO₃ the value decreases rapidly from one after 300 K. These perovskites are prospective candidates for thermoelectric applications.

研究立方包晶 BXO3（X = P、As、Sb、Bi）的电子、光学和热电特性：DFT 计算

在密度泛函理论（DFT）框架内研究了 BXO3（X = P、As、Sb 和 Bi）包晶的结构、电子、光学和热电特性。全电势线性化增强平面波方法采用了各种交换相关电势近似值来估计基态的物理特性。研究考察了 BXO3 包晶的基态稳定性，所有化合物都显示出立方结构的稳定性。在稳定阶段计算出的基态结构参数与现有文献十分吻合。我们的光学特性研究结果表明，BXO3（X = P、As、Sb 和 Bi）有可能用于光电设备的可见光和紫外区。除 BSbO3 具有直接带隙外，所研究的包晶都具有间接带隙能。值得注意的是，我们的研究结果表明，除 BPO3 外，BSbO3 和 BBiO3 在 100-800 K 的温度范围内的优越性（ZT）值接近于一。与此相反，BAsO3 的 ZT 值在 300 K 之后从 1 迅速下降。这些包晶有望成为热电应用的候选材料。

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.
