摘要：
In this work, we demonstrate the application of micro-Raman spectroscopy for the investigation of the neutral and charged domain walls in the congruent and MgO-doped lithium niobate single crystals. We present local changes of the intensity and frequency of three Raman lines in the vicinity of the domain walls and discuss the influence of the bulk screening of depolarization field on these parameters.
