Direct observation of locally modified excitonic effect within a moiré unit cell in twisted bilayer graphene
Ming Liu, Ryosuke Senga, Masanori Koshino +2
Bilayer graphene, forming moiré superlattices, possesses distinct electronic and optical properties derived from the hybridization of energy band and the emergence of van Hove sing…
Direct observation of the vanishing EELS cross section in graphene
Alberto Guandalini, Ryosuke Senga, Yung-Chang Lin +5
In transmission electron energy-loss spectroscopy, the cross section in 2D is quenched by kinematic effects once the momentum transfer becomes smaller than a critical value set by…
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…
