Abstract

We report in situ observation of the nucleation and growth of ferroelectric 180° domains in congruent LiNbO₃ crystals. The domains nucleate and grow as six-sided polygons. The wall velocity measured at a constant field shows a spike-like behavior with time, suggesting a strong pinning-depinning type of growth mechanism. This behavior is similar to the corresponding transient current measurement which also shows current spikes during domain reversal.
