A Review of Fe/Ni Doping Effects on Barium Strontium Titanate: Characterization and Insights

Abstract

Recent advancements in research, fueled by modern technologies, have garnered significant attention. Perovskite barium strontium titanate (BST), when doped with metals, has emerged as a promising material with vast potential for various applications. UV spectral analysis of metal-doped BST reveals that tunable band gaps can be achieved by varying annealing temperatures. Furthermore, the dielectric properties and impedance characteristics of Fe/Ni-doped BST highlight its potential in applications such as multilayer capacitors, PTC thermistors, piezoelectric devices, and energy storage systems.
