Abstract
The influence of electric field induced ferroelectricity (piezoelectricity) in SrTiO3 thin films on the capacitance of the Pt/SrTiO3/Pt MIM capacitors were investigated. The SrTiO3 thin film MIM capacitors show electric field induced resonance under dc electric field at specific frequencies. These piezoelectric resonant frequencies depend only on the stack structure of the capacitor, but are independent of the MIM area and the applied dc electric field strength.
