Comparative Solution Synthesis of Mn Doped (Na,K)NbO3 Thin Films

(K0.5Na0.5)NbO3 (KNN) is a promising lead‐free alternative for ferroelectric thin films such as Pb(Zr,Ti)O3. One main drawback is its high leakage current density at high electric fields, which has been previously linked to alkali non‐stoichiometry. This paper compares three acetate‐based chemical s...
