Optical properties of SrxBa1−xNb2O6 nanoscale films (x = 0.5 and 0.61) grown by RF-cathode sputtering in an oxygen atmosphere

The research findings of the phase composition, nanostructure and optical properties of strontium–barium niobate thin films are discussed. SrxBa1−xNb2O6 nanosized films (x = 0.5 and 0.61) were characterized by XRD, SEM and AFM studies. Reflective multi-angle ellipsometry and spectrophotometry were u...
