Influence of yttrium dopant on the structure and electrical conductivity of potassium sodium niobate thin films
KNN thin films with diverse yttrium concentration (mol % = 0, 0.1, 0.3, 0.5, 0.7 and 0.9) were fabricated using sol-gel spin coating technique. Doped KNN revealed that Y3+ was successfully doped into the ABO3 perovskite lattice without changing the phase formation of KNN. The thickness of the d...

| description | KNN thin films with diverse yttrium concentration (mol % = 0, 0.1, 0.3, 0.5, 0.7 and 0.9) were
fabricated using sol-gel spin coating technique. Doped KNN revealed that Y3+ was successfully doped
into the ABO3
perovskite lattice without changing the phase formation of KNN. The thickness of the
deposited layer of KNN produced with increasing dopant concentration was determined to be 200 nm
with dense and well-defined grains. Afterwards, the vibrational bonding and conductivity of KNN films
with diverse yttrium concentration were identified according to the charge compensation mechanism.
At high dopant concentration of > 0.5 mol %, O-Nb-O bonding was asymmetric and became distorted
due to B-site occupancy by yttrium dopant. Further investigation revealed that charge compensation
mechanism was shifted by increasing doping concentration. As a result, yttrium-doped KNN became
semi-conductive at low yttrium concentration. Meanwhile, at high concentration, yttrium-doped KNN
became an insulator and underwent ionic compensation |
