Simple and Rapid Fabrication of Thin Films by a Chelate Route
Figure 5
Ferroelectric hysteresis loops for NKN thin films grown using 20 mol % (N-20), 10 mol% Na+ excess (N-10), 0 mol% alkaline excess (NK-0), and 15 mol% K+ excess (K-15) in precursor solutions on Pt/TiO2/SiO2/Si substrate after annealing at 650°C.
