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…
Probing exciton dispersions of freestanding monolayer WSe2 by momentum resolved electron energy loss spectroscopy
Jinhua Hong, Ryosuke Senga, Thomas Pichler +1
Momentum resolved electron energy-loss spectroscopy was used to measure the dispersions of excitons in a free-standing monolayer of WSe2. Besides the parabolically dispersed valley…
Position and momentum mapping of vibrations in graphene nanostructures in the electron microscope
Ryosuke Senga, Kazu Suenaga, Paolo Barone +3
Propagating atomic vibrational waves, phonons, rule important thermal, mechanical, optoelectronic and transport characteristics of materials. Thus the knowledge of phonon dispersio…
