Synthesis and properties of free-standing monolayer amorphous carbon
Chee-Tat Toh, Hongji Zhang, Junhao Lin +12
Bulk amorphous materials have been studied extensively and are widely used, yet their atomic arrangement remains an open issue. Although they are generally believed to be Zacharias…
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…
Tunable Doping of Rhenium and Vanadium into Transition Metal Dichalcogenides for Two-Dimensional Electronics
Shisheng Li, Jinhua Hong, Bo Gao +10
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) with unique electrical properties are fascinating materials used for future electronics. However, the strong Fermi lev…
Electron spectroscopy of single quantum objects to directly correlate the local structure to their electronic transport and optical properties
Ryosuke Senga, Thomas Pichler, Kazu Suenaga
Physical property of a single quantum object is governed by its precise atomic arrangement. The direct correlation of localized physical properties with the atomic structures has b…
Proton and Li-Ion Permeation through Graphene with Eight-Atom-Ring Defects
Eoin Griffin, Lucas Mogg, Guang-Ping Hao +21
Defect-free graphene is impermeable to gases and liquids but highly permeable to thermal protons. Atomic-scale defects such as vacancies, grain boundaries and Stone-Wales defects a…
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…
