BaTiO₃: Barium Titanate Nanostructures and Thin Films for Photonics (Advanced Optical Materials 24/2020)

Artemios Karvounis, Rachel Grange and co-workers review the recent progress of photonic nanostructures and thin films based on barium titanate (see article number 2001249). Barium titanate is a noncentrosymmetric crystal utilised in a various spectrum of applications from nonlinear optics and biophotonics up to electro-optics and photonic waveguides. The significance of this material platform relies on the plethora of growth capabilities either through bottom-up or top-down methods. The strong electrooptic response, the intrinsic second-order nonlinearity, and the tunable optoelectronic properties configure a technological platform of high interest.
