MICROSTRUCTURE OF PEROVSKITE-TYPE OXIDE SINGLE CRYSTAL AND METHOD OF MANUFACTURING THE SAME, COMPOSITE PIEZOELECTRIC MATERIAL, PIEZOELECTRIC VIBRATOR, ULTRASONIC PROBE, AND ULTRASONIC DIAGNOSTIC APPARATUS

摘要

A method of manufacturing a microstructure of perovskite-type oxide single crystal having a desired composition and exhibiting excellent properties. The method includes the steps of: (a) forming a coating layer on a surface of a seed single crystal substrate, the coating layer containing the same metallic elements as those in a predetermined perovskite-type oxide; (b) forming a joint body having a micro-structured precursor of the predetermined perovskite-type oxide adhered to a surface of the coating layer; and (c) heat-treating the joint body to induce solid phase epitaxy, and thereby, single-crystallizing the precursor.
