摘要
We report on studies on writing of micro-and nanodomains and specified domain patterns by AFM-tip voltages U-DC in thin (0.5 mu m thick) ion-sliced LiNbO3 films embedded to SiO2/LiNbO3 substrates. A peculiar feature is an overlapping of domains as the distance between them decreases. Piezoelectric hysteresis loops were measured in a wide range of U-DC pulse durations. Domain dynamics and characteristics of hysteresis loops reveal marked distinctions from those observed so far in LiNbO3 films and bulk crystals. (C) 2015 AIP Publishing LLC.
