Abstract

Piezoelectric ceramic thin film has become worldwide attention as current used materials for the application contains hazardous substances. In this report, the alternative material for piezoelectric ceramic thin film which is various coating layer of alkali niobate through sol-gel technique is investigated. Alkali niobate are used as the raw material in this research. The requirement in this research is to analyse the physical and mechanical properties of various coating layer of Alkaline niobate. In this experiment, the raw materials were mix with 2-metoxyethanol and acetylacetone as solvent and chelating agent respectively to obtain 1.0M sol concentration, using Sol-gel technique at 2000 rpm for 30s. Sol precursor preparation and substrate preparation are fabricated and processed in parallels and both were combined in spin coating process. Sol precursor and prepared Ti/Pt substrate is then sputtered using spin coating machine. Coated substrate is then calcined at 350°C for 3 minutes and annealed at 650°C for 1 hour. The sample is then tested physically and mechanically in order to determine the physical and mechanical properties of rare earth doped KNN thin film. The test involves in this research X-ray diffraction (XRD), Raman spectroscopy and Scanning electron microscopic (SEM).
