Strain engineering of valley-polarized hybrid excitons in a 2D semiconductor
Abhijeet M. Kumar, Douglas J. Bock, Denis Yagodkin +11
Encoding and manipulating digital information in quantum degrees of freedom is one of the major challenges of today's science and technology. The valley indices of excitons in tran…

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…

Ultrafast photocurrents in MoSe probed by terahertz spectroscopy
Denis Yagodkin, Lukas Nadvornik, Oliver Gueckstock +3
We use the terahertz (THz) emission spectroscopy to study femtosecond photocurrent dynamics in the prototypical 2D semiconductor, transition metal dichalcogenide MoSe. We ident…
