Pulsed Laser Deposition $Na_{0.5}K_{0.5}NbO_{3}$ Thin Film

PLD 기법에 의한 $Na_{0.5}K_{0.5}NbO_{3}$ 박막 제작

Na-K-Nb system showed a number of ferroelectric phases in bulk ceramic. [001]-axis oriented single-phase Na$_{0.5}$K$_{0.5}$NbO$_3$ (NKN) thin film have been grown on LaA1O$_3$ substrates using KrF excimer laser. X-ray diffraction $\theta$-2$\theta$ scan, rocking curves, and $\phi$ scan data evidence highly c-axis oriented along the [001] direction.ion.
