Abstract :
Epitaxially a- and b-axis-oriented (Bi3.25Nd0.75)Ti3O12 (BNT-0.75) films and nanoplates have been fabricated on four Nb:TiO2(101) substrates with 0-0.79 mass% Nb by high-temperature sputtering. It is shown from piezoresponse scanning force microscopy (PFM) measurements that the effective piezoelectric coefficients (d33) at room temperature derived from the two linear gradients for the asymmetric displacement-voltage hysteresis loop are 11-13 pm/V.
