摘要：
Scanning force microscopy is used to investigate nanoscale ferroelectric domain engineering in near-stoichiometric lithium niobate (SLN) single crystals. The topography of the SLN single crystal was studied after polished to about 10 micron thickness. Dot patterns of the domain structure were fabricated by applying positive DC voltages of magnitude form 80 to 100 V with different pulse width from 0.5 to 20 s. The dot nanodomains of radius down to 200 nm were fabricated. With the increase of the magnitude of voltage and pulse width, feature size of switched domains increased to 940 mn.
