Characterization of electro-optic coefficients r13 , r23 and r33 in single crystalline BaTiO3 thin films
Résumé
We report experimental characterization of DC electro-optic coefficients r 13 , r 23 and r 33 in thin film single crystalline BaTiO3 on DyScO3 . The epitaxial BaTiO3 thin film is sandwiched between a SrRuO3 bottom electrode and an indium tin oxide (ITO) top electrode. We characterize the DC electro-optic coefficients r 13 , r 23 , and r 33 by the prism coupling method at 636.6 nm for the BaTiO3 thin film. The results show the DC coefficients r 13 = 4.2 pm/V, r 23 = 4.6 pm/V and r 33 = 9.0 pm/V.
