From: Fano resonance of Li-doped KTa1−xNbxO3 single crystals studied by Raman scattering
The temperature dependence of reduced intensity, I0, line shape parameter, q and FWHM, ГTO2 of the Fano resonance in (a) VV and (b) VH scattering spectra of the KLTN/0.05/0.27 crystal fitted by equation (2). The example of a fitted curve is shown in (c). (d) The temperature dependence of q−1 and ΓTO2 observed at the VV scattering geometry in the ferroelectric phase. The solid lines in (d) are guide to eyes.
