Bismuth titanate (Bi 4 Ti 3 O 12 ; BIT) -based ferroelectric materials are proposed from the view of the “Site-engineering”, where the Bi-site ions are substituted by lanthanoid ions (La 3+ and Nd 3+ ) and Ti-site ions by other ions with higher charge valence (V 5+ ). In the present study, influences of vanadium (V) - substitution for (Bi,M) 4 Ti 3 O 12 thin films [M = lanthanoid] on the ferroelectric properties are evaluated. V-substituted (Bi,M) 4 Ti 3 O 12 films have been fabricated using a chemical solution deposition (CSD) technique on the (111)Pt/Ti/SiO 2 /(100)Si substrate. Remnant polarization of (Bi,La) 4 Ti 3 O 12 and (Bi,Nd) 4 Ti 3 O 12 films has been improved by the V-substitution independent of the coercive field. The processing temperature of BLT and BNT films could also be lowered by the V-substitution.
