Abstract

A tetragonal barium titanate (BTO) thin film of high crystal quality with a c-axis oriented out of the plane was successfully grown at 500℃ on the strontium titanate(100) substrate using the physical vapor deposition technique. It showed epitaxial growth with a dense morphology and a low full width at half maximum value (FWHM) of 0.5° in the X-ray diffraction spectroscopy rocking curve measurements of the BTO(002) reflection. Using a modified Sénarmont method, the birefringence measurement of the BTO film revealed that it predominantly exhibits a quadratic and asymmetric electrooptic (EO) behavior in response to the applied DC electric field with an effective EO coefficient value of 1.94 × 10^-19 m²/V², providing useful insights on the BTO growth and its potential optoelectronics applications.
