Enabling valley selective exciton scattering in monolayer WSe2 through upconversion
Excitons, Coulomb bound electron-hole pairs, are composite bosons and their interactions in traditional semiconductors lead to condensation and light amplification. The much stronger Coulomb interaction in transition metal dichalcogenides such as WSe2 monolayers combined with the presence of the valley degree of freedom is expected to provide new opportunities for controlling excitonic effects....
متن کاملDirect measurement of exciton valley coherence in monolayer WSe2
In crystals, energy band extrema in momentum space can be identified by a valley index. The internal quantum degree of freedom associated with valley pseudospin indices can act as a useful information carrier, analogous to electronic charge or spin1–4. Interest in valleytronics has been revived in recent years following the discovery of atomically thin materials such as graphene and transition ...
متن کاملRoom-temperature Tamm-plasmon exciton-polaritons with a WSe2 monolayer
Solid-state cavity quantum electrodynamics is a rapidly advancing field, which explores the frontiers of light-matter coupling. Metal-based approaches are of particular interest in this field, as they carry the potential to squeeze optical modes to spaces significantly below the diffraction limit. Transition metal dichalcogenides are ideally suited as the active material in cavity quantum elect...
متن کاملskopos theory and translating strategies of csis in translaed literary texts from english into persian
abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
