Physical and electrical properties enhancement of rare-earth doped-potassium sodium niobate (KNN): A review

Alkaline niobate mainly potassium sodium niobate, (KxNa1-x) NbO3 (abreviated as KNN) has long attracted attention as piezoelectric materials as its high Curie temperature (Tc) and piezoelectric properties. The volatility of alkaline element (K, Na) is, however detrimental to the stoichiometry of K...
