Exploration of the ferroelectric properties of a new Titanium-based compound

ORAL

Abstract

Even though ferroelectric materials are well known and widely used in many applied fields, the families of compounds exhibiting ferroelectricity are just a few. Among them, BaTiO3 and its substitution-related compounds play a major role and have been widely investigated. We present here an experimental study on a new titanium-based perovskite structure. The synthesis and structural characterization (through XRD and Raman spectroscopy) of this material will be exposed, in excellent agreement with DFT calculations. We will demonstrate possible ferroelectricity at room temperature and discuss the probable microscopic mechanisms at play in this material.
