Integration of perovskite PZT thin films on diamond substrate without buffer layer

TLDR: In this article, the authors reported the successful deposition of PZT thin film directly on a diamond substrate without any buffer layer using the pulsed-laser deposition technique, but the perovskite phase was realized only under specific growth conditions.

Abstract: Integration of lead zirconate titanate (PZT) thin film on diamond substrate offers a great deal of potential for the application of multifunctional devices under extreme conditions. However, fabrication of perovskite PZT thin films on diamond substrate without a buffer layer has not been realized to date. We report for the first time on the successful deposition of PZT thin film directly on a diamond substrate without any buffer layer using the pulsed-laser deposition technique. The perovskite phase was realized only under specific growth conditions. X-ray diffraction and Raman studies confirmed the perovskite phase. The ferroelectric behaviour of the deposited PZT thin film was confirmed using piezo response microscope phase image and ferroelectric hysteresis loop.
