摘要: We report ferroelectric domain inversion in strontium barium niobate (SBN) single crystals by irradiating the surface locally with a strongly focused ultraviolet (UV) laser beam. The generated domains are investigated using piezoresponse force microscopy. propose simple model that allows predicting width as function of irradiation intensity, which indeed applies for both SBN and LiNbO3. Evidently, though fundamentally different, structure LiNbO3 can be engineered through similar UV irradiation.
