Second-Order Nonlinear Circular Dichroism in Square Lattice Array of Germanium Nanohelices
Grégoire Saerens, Günter Ellrott, Olesia Pashina +5
Second harmonic generation (SHG) is prohibited in centrosymmetric crystals such as silicon or germanium due to the presence of inversion symmetry. However, the structuring of such…
