Moiré Potential Impedes Interlayer Exciton Diffusion in van der Waals Heterostructures
Junho Choi, Wei-Ting Hsu, Li-Syuan Lu +16
The properties of van der Waals (vdW) heterostructures are drastically altered by a tunable moiré superlattice arising from periodic variations of atomic alignment between the laye…

Tailoring excitonic states of van der Waals bilayers through stacking configuration, band alignment and valley-spin
Wei-Ting Hsu, Bo-Han Lin, Li-Syuan Lu +6
Excitons in monolayer semiconductors have large optical transition dipole for strong coupling with light field. Interlayer excitons in heterobilayers, with layer separation of elec…
