Exciton mapping at subwavelength scales in two-dimensional materials
Luiz H. G. Tizei, Yung-Chang Lin, Masaki Mukai +5
Spatially resolved EELS has been performed at diffuse interfaces between MoS and MoSe single layers. With a monochromated electron source (20 meV) we have successfully prob…
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…
Momentum Conserved Ultrafast Charge Transfer Dynamics of Interlayer Excitons in vdW Heterostructures
Pranjal Kumar Gogoi, Yung-Chang Lin, Ryosuke Senga +9
Heterostructures comprising van der Waals (vdW) stacked transition metal dichalcogenide (TMDC) monolayers are a fascinating class of two-dimensional (2D) materials with unique prop…
