| 摘要 |
A piezoelectric resonator includes a piezoelectric layer having a first resonance frequency temperature coefficient of a first sign, a first and a second electrode, the piezoelectric layer being arranged between the first and second electrodes, and a compensation layer arranged between the first electrode and the piezoelectric layer, of a compensation material having a second resonance frequency temperature coefficient of a second sign opposite to the first one, wherein the compensation material is provided with a modification material to increase a conductivity of the compensation layer in a direction of the first electrode and the piezoelectric layer.
