Sensing capabilities of ultrathin BaTiO3 nanostructures toward carbon oxides based on optical signals

Due to the large presence of carbon oxide gases in both our environment and industry, there is an ongoing search for simple and efficient gas sensors. As a response to the current challenges toward lower limits of detection, in this work we propose a detection of optical signals from ultrathin BaTiO3 nanostructures as the basis for carbon oxides sensing. Based on density functional theory, we simulate the sensitivity of electrical and optical properties of the ultrathin BaTiO3 nanostructure with respect to different adsorption sites on the (001)-BaTiO3 surface. Significant changes in the optical activity, including absorption, reflection and EELS spectra, are detected. Supercell model study showed that optical signals follow a monotonous trend with respect to the molecule concentration. The changes are explained via charge transfer between the (001)-BaTiO3 surface and the adsorbed gas molecules. An insight into the physical and chemical nature of the processes at the nano-scale improves our understanding of the sensing mechanism. At the same time, the obtained results might pave a way to new easy-to-use but robust sensor designs.
