Published: Theoretical model of electro-optic effect in strained c-domain (Ba, Sr)TiO3 films

Our paper entitled “Theoretical Estimation of the Linear Electro-optic Effect in Compressively Strained c-domain (Ba, Sr)TiO3 Thin Films using a Phenomenological Thermodynamic Model” has been published in J. Ceram. Soc. Jpn. To estimate the EO coefficients, we considered not only the intrinsic EO effect but also the elasto-optic effect by converse piezoelectric response. We found that the EOresponse is mostly determined by the difference in temperature from the ferroelectric-to-paraelectric phase transition boundary modified by the strain.
