Optimizing the processing conditions of sodium potassium niobate thin films prepared by sol-gel spin coating technique
In the present study, potassium sodium niobate (KNN) thin films were synthesized by means of sol-gel spin coating method. Along with the synthesis, the effects of annealing temperature and various number of coating layers on both the structural and electrical properties were looked into. The resul...

description |
In the present study, potassium sodium niobate (KNN) thin films were synthesized by means of sol-gel spin
coating method. Along with the synthesis, the effects of annealing temperature and various number of coating
layers on both the structural and electrical properties were looked into. The results of the study revealed that the
annealing temperature had a great impact on the properties of KNN. In addition, the XRD diffractograms and
texture coefficient of the synthesized films confirmed that a highly oriented orthorhombic perovskite structure
was obtained at 650 °C, whereas at a relatively higher temperature (700 °C), a spurious phase of K4Nb6O17 was
evolved. In addition, the growth of KNN at 650 °C exhibited a reasonable resistivity value for piezoelectric
applications. Looking into the results, it was discovered that the KNN thin films also found to be dependent on a
number of coating layers. Field emission scanning electron microscopy (FESEM) showed that KNN with five
coating layers was highly crystalline, cracks-free, and had significantly more homogenous surface morphology
and the size of grains being uniform, the resistivity of KNN thin films improved with the increasing number of
coating layers i.e., up to five |
