Both ferroelectric Na0.5Bi0.5TiO3 (NBT) and K0.5Bi0.5TiO3 (KBT) are considered as the best known lead-free materials. In this experiment, we prepared NBT and KBT thin films on Pt/TiO2/SiO2/Si substrates by metalorganic solution deposition. The structural properties and surface morphologies were...

Lead-free Bi0.5(Na0.4K0.6)0.5TiO3 films have been synthesized by a chemical solution deposition method and deposited on p-Si(111) substrate by spin coating. Powder of the precursor solution heated at 650°C was studied by infrared scattering spectroscopy. The structural characteristics and...
