Magnetic and Light Dance: Research discovers that non-regenerative second harmonic generation disappears in 2D materials
Hg polarity plots for MNPSE3/graphene heterojunction (A) and MNPSE3 layers only (B). Credit: Li Bolin The research group recently discovered the disappearance of non-re-ricoral second harmonic generation (SHG) of MNPSE₃ when integrated into a two-dimensional (2D) antiferromagnetic MNPSE/graphene heterojunction. This study, published in Nano Letters, highlights the role of interface magnon plasmon coupling in this phenomenon. 2d van der waals…
