  1. 1. Preparation and Characteristics of Bi0.5Na0.5TiO3 based Lead-Free thin films by Pulsed Laser Deposition

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ge Jiang; [2018]
    Keywords : PLD method; piezoelectric thin film; electrical properties; PLD-metoden; piezoelektrisk tunnfilm; elektriska egenskaper;

    Abstract : Lead-based piezoelectric materials, such as PbZrxTi1-xO3 (PZT), have attracted considerable attention and have been widely used in actuators, sensors and transducers due to their excellent electric properties. However, considering the toxicity of lead and its oxides, environmentally friendly lead-free piezoelectric materials are attracting more attention as potential replacements for PZT. READ MORE
