We develop an optimized chemical synthesis route to obtain BaxSr1-xTiO3 (x=0, 0.50, 1.0) thin films with accurate stoichiometry control. The molar ratios of the precursors were altered to produce single crystalline cubic phase of SrTiO3, Ba0.5Sr0.5TiO3, and tetragonal phase BaTiO3 thin films on various substrates. The analyzed Raman spectrum for the BaxSr1-xTiO3 thin films on quartz substrates shows characteristic vibration modes at ~303, 515 and 716 cm-1. The active modes of BaTiO3 signify the tetragonal phase, which is important for its various technological advantages. The above findings are important for evaluating device compatibility of cost efficient solution processed BaxSr1-xTiO3 thin films. |
