Thickness effects of Bi0.89Ti0.11FeO3 thin films deposited on PbZr0.2Ti0.79Nb0.01O3 buffer layers

Ferroelectric and piezoelectric properties of lead-free BaTiO3 doped Bi0.5Na0.5TiO3 thin films from metal-organic solution deposition

“…A 10 mol% excess of sodium was used, to compensate for the loss of sodium via evaporation during the high-temperature annealing step. The BT solution was prepared with Ba(CH 3 COO) 2 and Ti[OCH(CH 3 ) 2 ] 4 , in a manner very similar to the method described above for the BNT solution. Finally an appropriate amount of HN(CH 2 CH 2 OH) 2 was added to each of the above two solutions with subsequent stirring for 2 h. Finally, the BNT and BT solutions were mixed together and stirred for an additional 12 h to obtain a yellow BNT-BT solution.…”

“…These materials have some shortcomings, however, including imprint problems, lead toxicity, and especially fatigue when cycled over 10 7 times [2]. All of these deficits serve to limit the applications of PZT ceramics.…”
