Effect of crystallization temperature on microstructure and ferroelectric properties of (Bi,Nd)4Ti3O12 thin films prepared by chemical solution deposition

Effect of precursor solution concentration on the grain orientation of Bi3.15Nd0.85Ti3O12thin films

“…(1 0 4)/(0 1 4) orientation, whereas it was 10 • C min −1 for the predominantly c-axis-oriented films. Hou and Shen [11] found that at the lower annealing temperature of 650 • C, the BNT thin films exhibited a random orientation with the weak (0 0 l), but relativly strong (1 1 7) diffraction peaks. With increasing crystalline temperature, the (0 0 l) diffraction peaks became stronger.…”

Control of morphology and orientation of grains in chemical-solution-deposited Bi3.15Nd0.85Ti3O12 thin films

“…However, it suffers a normally low remanent polarization P r and severe polarization suppression after $10 6 switching cycles. Therefore, Bi 3.15 Nd 0.85 Ti 3 O 12 (BNT), as a member of rare-earth-cation-modified bismuth titanate, has recently attracted considerable attention due to its enhanced P r and improved fatigue endurance [6][7][8][9][10].…”

“…Lu et al [12] suggested that the different crystallographic orientations of the BNT thin films could be controlled by heating at different rates. Hou and Shen [7] found that at the lower annealing temperature of 650 1C, the BNT thin films exhibited a random orientation with weak (0 0 l) but relatively strong (117) diffraction peaks. Chen et al [13] considered enhanced a-axis-oriented crystal growth occurred when the crystallization was performed on every spin-coated layer with sufficiently thin thickness.…”
