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…

Excitons under large pseudomagnetic fields
Denis Yagodkin, Kenneth Burfeindt, Zakhar A. Iakovlev +7
Excitons in Transition Metal Dichalcogenides (TMDs) acquire a spin-like quantum number, a pseudospin, originating from the crystal's discrete rotational symmetry. Here, we break th…

Strain fingerprinting of exciton valley character
Abhijeet Kumar, Denis Yagodkin, Roberto Rosati +13
Momentum-indirect excitons composed of electrons and holes in different valleys define optoelectronic properties of many semiconductors, but are challenging to detect due to their…
