Microstrutural, Optical and electro-optical Properties Of Ba0.5Sr0.5TiO3 Thin Film Deposited By Pulsed Laser Deposition For Active Low Loss Waveguide Applications

Barium Strontium Titanate (Ba0.5Sr0.5TiO3 or BST) films were grown by means of a reactive pulsed laser deposition technique on SiO2/Si substrates. Microstructural and surface morphology of BST films were characterized by X-ray diffraction (XRD) scanning electron microscopy (SEM) and atomic force microscopy (AFM).
