Two dimensional transition metal chalcogenides have multi valley structures in their energy bands, giving them electron valley degrees of freedom, making them an ideal platform for studying multi body interactions. As the main mechanism of valley depolarization, the valley scattering process of free electrons or bound excitons is crucial for exploring excited state electron phonon interactions and...
