Abstract Li 1− x Nb 1+ x/5 O 3 (where x= 0, 0.025, 0.045, 0.075) ferroelectric ceramics were
prepared by the solid-state reaction method; X-ray diffraction patterns indicate that single …

Hydrogen incorporation during crystal growth or other treatment has attracted research
interest for a long time, but the diffusion paths and the role of additional defect sites within …

We demonstrate second-harmonic generation in a fiber-coupled periodically poled titanium
in-diffused lithium niobate waveguide over the temperatures range from 292 to 4.4 K. We …

The electronic conductivity was measured in single crystals of lithium niobate and lithium
