Spin/valley coupled dynamics of electrons and holes at the interface
Abhijeet Kumar, Denis Yagodkin, Nele Stetzuhn +6
The coupled spin and valley degrees of freedom in transition metal dichalcogenides (TMDs) are considered a promising platform for information processing. Here, we use a TMD heteros…
