Research Abstract |
a- and b-axis-oriented Bi3.25Nd0.75Ti3O12 (BNT-0.75) and Bi3.25Nd0.75-xEuxTi3O12 (BNEuT, x = 0-0.75) films of 3.0 um thickness were fabricated on conductive Nb:TiO2(101) substrates containing 0-0.79 mass% Nb by high-temperature sputtering. The optimal sputtering conditions (excess Bi2O3, deposition temperature, gas pressure and effective power density) to fabricate the ferroelectric nanoplates were investigated. By evaluating the physical properties of the resultant bismuth layer-structured ferroelectric nanoplates, it was demonstrated that the developed nanoplates had the potential as microelement materials for ferro- and piezoelectric, and multiferroic applications.
