Effect of amphoteric dopant on the dielectric and structural properties of yttrium doped potassium sodium niobate thin film
The amphoteric dopant effects on dielectric and structural properties of KNN were studied. The trace amounts of dopant were incorporated into the KNN lattice and formed the orthorhombic perovskite structure. The distribution of yttrium dopant on the perovskite lattice is responsible for enhancemen...

| description | The amphoteric dopant effects on dielectric and structural properties of KNN were studied. The trace
amounts of dopant were incorporated into the KNN lattice and formed the orthorhombic perovskite
structure. The distribution of yttrium dopant on the perovskite lattice is responsible for enhancement of
dielectric behaviors of KNN films. The dielectric loss is reduced from 0.18% to 0.0125%, owing to the
distribution of yttrium dopant at A-site lattice. Meanwhile, the tendency of Y3þ to occupy the B-site
lattice at high dopant concentration causes an increase in dielectric loss. The particles size of the KNN at
0.5 mol% yttrium was found to be uniform while porous structures were formed with increasing dopant
concentration. |
