Observation of forbidden phonons, Fano resonance and dark excitons by resonance Raman scattering in few-layer WS2
The optical properties of the two-dimensional (2D) crystals are dominated by tightly bound electron–hole pairs (excitons) and lattice vibration modes (phonons). The exciton-phonon interaction is fundamentally important to understand the optical properties of 2D materials and thus helps to develop em...
