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…
Momentum-dependent oscillator strength crossover of excitons and plasmons in two-dimensional PtSe2
Jinhua Hong, Mark Kamper Svendsen, Masanori Koshino +4
The 1T-phase layered PtX2 chalcogenides has attracted widespread interest due to its thickness dependent metal-semiconductor transition driven by strong interlayer coupling. While…
Deciphering the Intense Post-Gap Absorptions of Monolayer Transition Metal Dichalcogenides
Jinhua Hong, Masanori Koshino, Ryosuke Senga +3
Rich valleytronics and diverse defect-induced or interlayer pre-bandgap excitonics have been extensively studied in transition metal dichalcogenides (TMDCs), a system with fascinat…
The structure and local chemical properties of boron-terminated tetravacancies in hexagonal boron-nitride
Ovidiu Cretu, Yung-Chang Lin, Masanori Koshino +3
Imaging and spectroscopy performed in a low-voltage scanning transmission electron microscope (LV-STEM) are used to characterize the structure and chemical properties of boron-term…
