2D Excitonics with Atomically Thin Lateral Heterostructures
S. Shradha, R. Rosati, H. Lamsaadi +18
Semiconducting transition metal dichalcogenides (TMDs), such as MoSe and WSe, exhibit unique optical and electronic properties. Vertical stacking of layers of one or more T…
Tuning relaxation and nonlinear upconversion of valley-exciton-polaritons in a monolayer semiconductor
Hangyong Shan, Jamie M. Fitzgerald, Roberto Rosati +9
Controlling exciton relaxation and energy conversion pathways via their coupling to photonic modes is a central task in cavity-mediated quantum materials research. In this context,…
Impact of charge transfer excitons on unidirectional exciton transport in lateral TMD heterostructures
Roberto Rosati, Sai Shradha, Julian Picker +3
Lateral heterostructures built of monolayers of transition metal dichalcogenides (TMDs) are characterized by a thin 1D interface exhibiting a large energy offset. Recently, the for…
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…
