Resonator with intrinsic second harmonic cancellation

The invention relates to a resonator with intrinsic second harmonic cancellation. The resonator may include a first electrode, a second electrode, and a piezoelectric material between the first electrode and the second electrode, wherein the piezoelectric material is formed by manufacturing the piezoelectric material having a compression axial vector (C axial vector) oriented in a first direction and applying an electric field across the piezoelectric material to modify the direction of the C axial vector to be oriented in a second direction. The second direction may be anti-parallel to the first direction. 本公开涉及一种具有固有二次谐波抵消的谐振器。所述谐振器可包含第一电极、第二电极及所述第一电极与所述第二电极之间的压电材料，其中所述压电材料通过制造具有沿第一方向定向的压缩轴向量(C轴向量)的所述压电材料及跨越所述压电材料施加电场以将所述C轴向量的方向修改为沿第二方向定向而形成。所述第二方向可反平行于所述第一方向。
