Dual-channel charge transfer doping of graphene by sulfuric acid
Kwnaghee Park, Sunmin Ryu
Two-dimensional materials represented by graphene and transition metal dichalcogenides undergo charge transfer (CT) processes and become hole-doped in strong mineral acids. Nonethe…
Redox and Molecular Diffusion in 2D van der Waals Space
Haneul Kang, Kwanghee Park, Sunmin Ryu
Understanding charge transfer (CT) between two chemical entities and subsequent change in their charge densities is essential not only for molecular species but also for various lo…
Optical Imaging of Chemically and Geometrically Controlled Interfacial Diffusion and Redox in 2D van der Waals Space
Haneul Kang, Sunmin Ryu
Molecular motions and chemical reactions occurring in constrained space play key roles in many catalysis and energy storage applications. However, its understanding has been impede…
Extraordinary Photostability and Davydov Splitting in BN-Sandwiched Single-Layer Tetracene Molecular Crystals
Seonghyun Koo, Ina Park, Kenji Watanabe +3
Two-dimensional molecular crystals have been beyond the reach of systematic investigation because of the lack or instability of their well-defined forms. Here, we demonstrate drast…
