Abstract

The nanodomain reversal characteristics of congruent LiTaO₃ (CLT) single crystal were discussed. It was observed that fast nanosecond domain switching was achieved by reducing the sample thickness. A polarization inverted domain dot with a radius of 7.9 nm was obtained by application of 4 ns 10 V pulse. Analysis show that the speed of polarization reversal was closely related to the thickness of the medium.
