Insights into mechanism of the symmetry dependent SHG properties in low dimensional KNbO3 structures Tianhui Wu, Baipeng Yin, Zhenpan Bian, Yahui Gao, Jianmin Gu and Desong Wang Abstract The second harmonic generation (SHG) response of low-dimensional nanomaterials are of significant importance for fundamental science and technological applications, which is potential dependence on structural symmetry and high-density surface defects, e.g., body contribution and surface contribution.
