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.
