Effects of annealing dwell time on piezoelectric properties of KNN thin films: Phase insensitive behavior

Open Ceramics
Amorphous potassium sodium niobate (KNN) thin films were deposited onto Pt/Ti/SiO2/Si substrates at 200 °C using magnetron sputtering. The resultant films were then annealed in an alkali metal element atmosphere formed by alkali metal carbonates.

Sodium Potassium Niobate-Based Piezoelectrics Sintered in Humid Air

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control
While the consequences of humidity during solid-state processing of sodium potassium niobate-based lead-free piezoelectric powders are well established, the effect of humidity at later fabrication steps is less known. This study assesses the effect of humidity on the sintering and functional properties of 0.06LiNbO3-0.94(K0.5Na0.5)NbO3 (LKNN).
