摘要

采用固态晶体生长法生长出c取向(K0.5Na0.5)NbO3单晶。c方向的生长速度比c方向的快。单极应变曲线斜率为127 pm/V，大于c取向晶体的77 pm/V，但小于c取向晶体的211 pm/V。这些结果有助于制作成分更复杂的具有更大压电性能的(K,Na) nbo3基单晶。

Fabrication of <111>c-oriented (K0.5Na0.5)NbO3 Single Crystal by Solid-State Cyrstal Growth Method

A <111>c-oriented (K0.5Na0.5)NbO3 single crystal was grown by a solid-state crystal growth method. A faster growth rate in the <111>c direction was observed than in the <100>c direction. The slope of the unipolar strain curve was 127 pm/V, which was larger than that of a <110>c-oriented crystal (77 pm/V) but smaller than that of a <100>c-oriented crystal (211 pm/V). These results are useful for the fabrications of compositionally more complicated (K,Na)NbO3-based single crystals with larger piezoelectric properties.
