Electrical properties and impedance spectroscopy of modified potassium sodium niobate ceramics
Proceedings of ISAF-ECAPD-PFM 2012, 2012 Lead-free potassium sodium niobate (KNN) ceramics were prepared with lithium modification. Copper oxide was also added as sintering aid. Impedance spectroscopy was used as a tool to analyze electrical behavior of ceramics as a function of frequency from 100 Hz to 10 MHz at various temperatures. © 2012 IEEE.

The effect of surface termination on dielectric nonlinearity in potassium sodium niobate thin films
Journal of the American Ceramic Society, Volume 108, Issue 11, November 2025.Abstract The impact of alkali‐rich and alkali‐depleted surface terminations on dielectric nonlinearity and ferroelectric properties was investigated in sputtered K0.5Na0.5NbO3 (KNN) films. For the alkali depleted surface termination, a ∼3 nm thick amorphous interfacial layer was found near the top electrode.
