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…

Degradation of the electrical conductivity of charged domain walls in reduced lithium niobate crystals

In this work, the effect of long-term room temperature exposure on the electrical conductivity of the charged domain wall (CDWs) in nonpolar x-cut congruent lithium niobate (LiNbO3, LN) crystals has



Poling thin-film x-cut lithium niobate for quasi-phase matching with sub-micrometer periodicity

Quasi-phase-matched grating structures in lithium niobate waveguides with sub-micrometer periodicities will benefit the development of short-wavelength nonlinear optical devices. Here, we report on

Tip-induced domain growth on the non-polar cuts of lithium niobate single-crystals

Currently, ferroelectric materials with designed domain structures are considered as a perspective material for new generation of photonic, data storage, and data processing devices. Application of

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

Subsurface nanodomains with in-plane polarization in uniaxial ferroelectrics via scanning force microscopy

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

A technique for realizing multi-centimeter-long lithium niobate on insulator (LNOI) waveguides with a propagation loss as low as 0.027 dB/cm is developed, enabling high-throughput manufacturing of large-scale LNOI-based photonic integrated circuits.

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

Ferroelectric domain wall memory with embedded selector realized in LiNbO3 single crystals integrated on Si wafers

It is shown that dead layers with low Li concentration located at the surface of LiNbO3 ferroelectric materials can function as unipolar selectors and an integrated one selector–one resistor device is realized.

Domain inversion in LiNbO3 and Zn-doped LiNbO3 crystals by the electron-beam irradiation of the nonpolar Y-surface

Individual domains and domain gratings were fabricated on nonpolar Y-cuts of LiNbO3 and LiNbO3-Zn crystals by electron beam irradiation. The domains which nucleated in the irradiation points are
