Resonant valley-specific exciton-phonon coupling in layered SnS
The authors demonstrate here that different valleys in anisotropic 2D materials exhibit dramatically different phonon coupling hierarchies. This valley-specific reorganization pushes valleytronics in a new direction by establishing phonon scattering as an intrinsic valley fingerprint, enabling phonon-mediated valley control beyond conventional methods. The work creates connections between valleytronics and phonon physics by showing valley identity is fundamentally encoded in electron-phonon coupling strength, transforming phonons from passive dissipation channels to active players in valley manipulation, opening new pathways for valleytronic technologies.
