Probing Noncentrosymmetric 2D Materials by Fourier Space Second Harmonic Imaging

Second-harmonic generation (SHG) has been established as a powerful tool for probing noncentrosymmetric materials. In the typical implementation, the SHG intensity is detected while rotating the polarization of the incident laser field and of the second harmonic relative to the sample. Although effe...
