On-Stack Two-Dimensional Conversion of MoS2 into MoO3
Taeg Yeoung Ko, Areum Jeong, Wontaek Kim +10
Chemical transformation of existing two-dimensional (2D) materials can be crucial in further expanding the 2D crystal palette required to realize various functional heterostructure…
Structural and optical properties of single- and few-layer magnetic semiconductor CrPS4
Jinhwan Lee, Taeg Yeoung Ko, Jung Hwa Kim +7
Atomically thin binary 2-dimensional (2D) semiconductors exhibit diverse physical properties depending on their composition, structure and thickness. By adding another element in t…
Optical Probing of Electronic Interaction between Graphene and Hexagonal Boron Nitride
Gwanghyun Ahn, Hye Ri Kim, Taeg Yeoung Ko +5
Even weak van der Waals (vdW) adhesion between two-dimensional solids may perturb their various materials properties owing to their low dimensionality. Although the electronic stru…
Water-Gated Charge Doping of Graphene Induced by Mica Substrates
Jihye Shim, Chun Hung Lui, Taeg Yeoung Ko +4
We report on the existence of water-gated charge doping of graphene deposited on atomically flat mica substrates. Molecular films of water in units of ~0.4 nm-thick bilayers were f…
Raman Spectroscopy Study of Annealing-Induced Effects on Graphene Prepared by Micromechanical Exfoliation
Jieun Song, Taeg Yeoung Ko, Sunmin Ryu
In this note, we report a Raman spectroscopy study of annealing-induced effects on graphene samples prepared by the microexfoliation method. It was shown that randomly located adhe…
