Abstract

The conditions for optimal excitation of piezoceramic transducers are determined from the equality of the bias and conduction currents in a metal-polar insulator-metal (MIM) structure under an external electric field. Charge-carrier injection from the cathode is shown to affect the electric field strength distribution along the thickness of the insulator and the integral characteristic, i.e., the capacitance of thin-layer structures. Numerical computation indicates that in the case of piezoceramic plates 0.4–0.5 mm thick electron emission from the cathode is possible at voltages of 5–8 V.
