Single Crystalline Silver Films for Plasmonics: From Monolayer to Optically Thick Film
Fei Cheng, Chien-Ju Lee, Junho Choi +7
Epitaxial growth of single crystalline noble metals on dielectric substrates has received tremendous attention recently due to their technological potentials as low loss plasmonic…
Moiré Excitons in Van der Waals Heterostructures
Kha Tran, Galan Moody, Fengcheng Wu +19
In van der Waals (vdW) heterostructures formed by stacking two monolayer semiconductors, lattice mismatch or rotational misalignment introduces an in-plane moiré superlattice. Whil…
Routing Valley Excitons in a Monolayer MoS2 with a Metasurface
Liuyang Sun, Chun-Yuan Wang, Alexandr Krasnok +8
Excitons in monolayer transition metal dichalcogenides (TMDs) are formed at K and K' points at the boundary of the Brillouin zone. They acquire a valley degree of freedom, which ma…
