Abstract
A piezoelectric material includes a first material layer including a polycrystalline lead zinc niobate-lead zirconate titanate material arranged in a 001 crystal direction; and a second material layer including a mono-crystalline material having a 001 crystal face, wherein the lead zinc niobate-lead zirconate titanate and the mono-crystalline material are different. Also a piezoelectric device including the piezoelectric material.
