Effects of annealing temperature on the properties of potassium sodium niobate films grown by RF magnetron sputtering

Potassium sodium niobate (KNN) is considered a promising alternative to conventional lead-based piezoelectric materials due to its high piezoelectric performance and environmental friendliness. However, owning to the volatility of alkali elements, the fabrication of KNN materials, especially thin films, remains challen...
