Abstract

Graded ferroelectric materials have attracted great attention because of their peculiar properties arising from the evolution of their microscopic structure. Graded bulk materials are advantageous because of their unique effects that can only be observed in bulk samples. A tetragonal KTa_1-xNb_xO₃ single crystal with graded composition (GC) was designed and grown with the goal of exploring the effects of GC on the macroscopic properties of the crystal. The crystal was produced via the top-seed solution growth method. A mechanism of the formation of an internal electric field induced by GC was elucidated, and an enhancement of the strain was observed as a result of the internal electric field.
