Activation and Detection of Forbidden Low‐Frequency Raman Modes in MoS2 by Near‐Field Gradient Illumination

open access: yesLaser &Photonics Reviews, EarlyView.
Low‐frequency Raman‐forbidden interlayer phonons in 2D materials are typically hidden by selection rules. Here, we demonstrate that plasmonic near‐field gradients can activate and detect these forbidden low‐frequency modes in a few‐layer MoS2 sample, unveiling a gradient‐driven mechanism for revealing hidden interlayer vibrations and breaking symmetry.
