Here we report that ferroelectric NbOI2 nanosheets exhibit giant second-harmonic generation with conversion efficiencies that are orders of magnitude higher than commonly reported nonlinear crystals. The nonlinear response scales with layer thickness and is strain- and electrical-tunable; a record >0.2%...
The single crystals poled along [001] of the original cubic direction possess giant electromechanical coupling factor k 31 over 80% and piezoelectric d 31 constant nearly m 1700 pC/N. These giant k 31 and d 31 constants results from the control of ferroelectric domain configuration. PZNT91/09...

β-Terbium molybdate is ferroelectric, ferroelastic and paramagnetic at room temperature. Large single crystals are easily grown by the Czochralski technique. The properties of β-Tb 2(MoO 4) 3 are very similar to those of β-Gd 2(MoO 4) 3.DOI...
Abstract The discoveries of ferromagnetic and ferroelectric two-dimensional (2D) materials have dramatically inspired intense interests due to their potential in the field of spintronic and nonvolatile memories. This review focuses on the latest 2D ferromagnetic and ferroelectric materials that have been ...
It is the intension of this review article to serve as a resource for those who are interested in basic research and practical applications of these relaxor-PT single crystals. In addition, possible mechanisms of giant piezoelectric properties in these domain-engineered relaxor-PT systems will be ...
