a XRD measurement at room temperature. The signal from the secondary phase is marked with asterisks (*). b SEM back-scattered electron (BSE) image of as-sintered Li-substituted KNbO3 sample. The scale bar is 5 μm. c Temperature-dependent relative permittivity measured at 10 kHz. d Raman spectra measured at room temperature. Symbols T, B, and S represent translational, bending, and stretching modes.
