We reported on a graphical domain engineering technique with the capability to fabricate macroscale domain structures with nanoscale spatial resolution in non-polar-cut lithium niobate thin film on insulators through the biased probe tip of scanning atomic force microscopy. It was found that the domain writing process is asymmetric with respect to the spontaneous polarization Ps even though the tip-induced poling field is mirror-symmetric. Various domain structures, with a dimension larger than…

Precise, reproducible nano-domain engineering in lithium niobate crystals

We present a technique for domain engineering the surface of lithium niobate crystals with features as small as 100 nm. A film of chromium (Cr) is deposited on the lithium niobate surface and

Domain formation and polarization reversal under atomic force microscopy-tip voltages in ion-sliced LiNbO3 films on SiO2/LiNbO3 substrates

We report on studies on writing of micro- and nanodomains and specified domain patterns by AFM-tip voltages UDC in thin (0.5 μm thick) ion-sliced LiNbO3 films embedded to SiO2/LiNbO3 substrates. A

Ferroelectric nanodomains can be created by the application of a bias voltage to the sharp conducting tip of a scanning force microscope (SFM) contacting the sample surface. Since an inhomogeneous

Long Low-Loss-Litium Niobate on Insulator Waveguides with Sub-Nanometer Surface Roughness

Domain wall nanoelectronics

Domains in ferroelectrics were considered to be well understood by the middle of the last century: They were generally rectilinear, and their walls were Ising-like. Their simplicity stood in stark
