Abstract
In this study, we have prepared PLT thin films having various La concentrations by using sol-gel method and studied on the effect of La concentration on the electrical properties of PLT thin films. As the La concentration increases from 5mol% to 28mol%, the dielectric constant at 10kHz increases from 428 to 761, while the loss tangent decreases from 0.063 to 0.024. Also, the leakage current density at 150kV/cm has a tendency to decrease from 6.96
La 농도에 따른 PLT 박막을 sol-gel법으로 제작하여, La 농도가 PLT 박막의 전기적 특성에 미치는 영양을 조사하였다. La 농도가 5 mol%에서 28 mol%로 증가함에 따라 10KHz의 주파수에서 비유전률은 428에서 761로 증가하였고 유전손실은 0.063에서 0.024로 감소하였으며, 누설전류밀도는 150kV/cm의 전기장에서 6.96
