Approaching Piezoelectric Response of Pb-Piezoelectrics in Hydrothermally Synthesized Bi-0.5(Na1-xKx)(0.5)TiO3 Nanotubes

Ghasemian, Mohammad Bagher; Rawal, Aditya; Liu, Yun; Wang, Danyang

Description

A large piezoelectric coefficient of 76 pm/V along the diameter direction, approaching that of lead-based piezoelectrics, is observed in hydrothermally synthesized Pb-free Bi0.5(Na0.8K0.2)0.5TiO3 nanotubes. The 30–50 nm diameter nanotubes are formed through a scrolling and wrapping mechanism without the need of a surfactant or template. A molar ratio of KOH/NaOH = 0.5 for the mineralizers yields the Na/K ratio of ∼0.8:0.2, corresponding to an orthorhombic–tetragonal (O–T) phase boundary...[Show more]
