Abstract :
This paper describes a new high coupling piezoelectric crystal of KNbO3 as well as practically used piezoelectric crystals such as LiNbO3 and LiTaO3, focusing on the orientation dependence of piezoelectric properties, domain structures, and various applications. Another related topic of this paper is domain inversion induced by some heat treatment of ferroelectric crystals and its applications.
