High contrast materials, i.e., materials with a high refractive index and low optical loss, are of wide interest for nanophotonics metasurface designs at near infrared wavelengths. We explore aluminum antimonide (AlSb) as nanophotonic material, using the design gratings (HCGs) loss dielectric mirrors an example. The refraction absorption coefficient AlSb in visible wavelength range enable HCGs ...

A thermodynamic model of electrolyte solutions has been used as a tool for equilibrium calculations in the Na-Bi-Ti-H2O and K-Bi-Ti-H2O systems. To perform the calculations, unknown standard-state properties for Na0.5Bi0.5TiO3 (NBT), K0.5Bi0.5TiO3 (KBT) and other solid compounds that exist in these systems were established. As a result of the calculations, stability and yield diagrams of the in...
