Domain switching by electron beam irradiation of Z+-polar surface in Mg-doped lithium niobate

Domain switching by electron beam irradiation of Z+-polar surface in Mg-doped lithium niobate

The appearance of the static domains with depth above 200 μm in the bulk of MgO-doped lithium niobate single crystals as a result of focused electron beam irradiation of Z+-polar surface was demonstrated. The created domain patterns were visualized by high-resolution methods including piezoresponse...

Zusammenfassung:The appearance of the static domains with depth above 200 μm in the bulk of MgO-doped lithium niobate single crystals as a result of focused electron beam irradiation of Z+-polar surface was demonstrated. The created domain patterns were visualized by high-resolution methods including piezoresponse force microscopy, scanning electron microscopy, and confocal Raman microscopy. The main stages of the domain structure formation were revealed and explained in terms of the original model.
