Investigation of dielectric characteristics and tunability of Ba0.8Sr0.2TiO3

Abstract

It's been years ferroelectric materials has become a popular fields for research. Many methods were used for the barium strontium titanate (BST) preparation like sol-gel method, radio frequency (RF) magnetron sputtering, metal organic chemical vapor deposition (MOCVD), pulsed laser deposition, and soft solution processing. In this work, sol-gel method was used for the BST preparation. The main focus in this paper is on the dielectric properties of Ba0.8Sr0.2TiO3. Dielectric constant, dielectric loss and tunability of the Ba0.8Sr0.2TiO3 were done in the experiment. As conclusion, the dielectric constant and tunability exhibit lower value compared the previous work; Ba0.7Sr0.3TiO3. However, Ba0.8Sr0.2TiO3 has a lower dielectric loss.
