Hydrothermal growth of piezoelectrically active lead-free (Na,K)NbO3–LiTaO3 thin films†
Abstract
Single phase, lead-free thin films based on the (Na,K)NbO3–LiTaO3 solid solution near the morphotropic phase boundary are grown hydrothermally at 130 °C for the first time. Formation of the unwanted Na-rich phase normally occurring during
