First-principles computational study reveals linear and non-linear optical responses in ferroelectric polyvinylidene fluoride, indicating potential mechanisms behind experimental discrepancies.
We report our first-principles studies on the linear and non-linear optical properties of ferroelectric polyvinylidene fluoride crystal. Calculated values of the refractive indices agree well with experiments. As regards the second-harmonic-generation coefficients, theoretical values are larger than experimental ones. Possible reasons for the discrepancy are discussed.
