Valley-dependent emission patterns enabled by plasmonic nanoantennas
Tobias Bucher, Jingshi Yan, Jan Sperrhake +12
Selective control over the emission pattern of valley-polarized excitons in monolayer transition metal dichalcogenides is crucial for developing novel valleytronic, quantum informa…
Role of Coherence in Polarization Response of Hybrid Monolayer MoS-Gold Nanoparticle Systems
Laura Valencia Molina, Zlata Fedorova, Angela Barreda +12
Monolayers of transition metal dichacogenides show strong second-order nonlinearity and symmetry-driven selection rules from their three-fold lattice symmetry. This process resembl…
Influence of resonant plasmonic nanoparticles on optically accessing the valley degree of freedom in 2D semiconductors
Tobias Bucher, Zlata Fedorova, Mostafa Abasifard +10
The valley degree of freedom is one of the most intriguing properties of atomically thin transition metal dichalcogenides. Together with the possibility to address this degree of f…
