Dimensional Control of Excitonic Interactions in Exfoliated 2D Molecular Crystals
Jonghyun Son, Seonghyun Koo, Daniel Yim +17
Two-dimensional (2D) materials provide unique opportunities to tailor excited-state properties through reduced dimensionality, altered dielectric screening and layer-dependent stru…
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…
Interface-Confined Doubly Anisotropic Oxidation of Two-Dimensional MoS2
Yejin Ryu, Wontaek Kim, Seonghyun Koo +4
Despite their importance, chemical reactions confined in a low dimensional space are elusive and experimentally intractable. In this work, we report doubly anisotropic, in-plane an…
Redox-Governed Charge Doping Dictated by Interfacial Diffusion in Two-Dimensional Materials
Kwanghee Park, Haneul Kang, Seonghyun Koo +2
Controlling extra charge carriers is pivotal in manipulating electronic, optical, and magnetic properties of various two-dimensional (2D) materials. Nonetheless, the ubiquitous hol…
Varying Electronic Coupling at Graphene-Copper Interfaces Probed with Raman Spectroscopy
Jieun Choi, Seonghyun Koo, Myeongin Song +3
As the synthesis of graphene on copper became one of the primary preparation methods for both fundamental research and industrial application, Raman spectra of graphene/Cu systems…
