Angstrom-wide conductive channels in black phosphorus by Cu intercalation
Suk Woo Lee, Lu Qiu, Jong Chan Yoon +8
Intercalation is an effective method to improve and modulate properties of two-dimensional materials. Even so, spatially controlled intercalation at atomic scale, which is importan…
Crystallographic Reconstruction Driven Modified Mechanical Properties in Anisotropic Rhenium Disulfides
Jung Hwa Kim, Xinyue Dai, Feng Ding +1
Atomic-scale investigation on mechanical behaviors is highly necessary to fully understand the fracture mechanics especially of brittle materials, which are determined by atomic-sc…
Polytypism in Few-Layer Gallium Selenide
Soo Yeon Lim, Jae-Ung Lee, Jung Hwa Kim +6
Gallium selenide (GaSe) is one of layered group-III metal monochalcogenides, which has an indirect bandgap in monolayer and direct bandgap in bulk unlike other conventional transit…
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…
Complete determination of crystallographic orientation of ReX2 (X=S, Se) by polarized Raman spectroscopy
Yun Choi, Keunui Kim, Soo Yeon Lim +5
Polarized Raman spectroscopy on few-layer ReS2 and ReSe2 was carried out to determine the crystallographic orientations. Since monolayer ReX2 (X=S or Se) has a distorted trigonal s…
Chemically Induced Transformation of CVD-Grown Bilayer Graphene into Single Layer Diamond
Pavel V. Bakharev, Ming Huang, Manav Saxena +12
Notwithstanding numerous density functional studies on the chemically induced transformation of multilayer graphene into a diamond-like film, a comprehensive convincing experimenta…
Determination of the thickness and orientation of few-layer tungsten ditelluride using polarized Raman spectroscopy
Minjung Kim, Songhee Han, Jung Hwa Kim +3
Orthorhombic tungsten ditelluride (WTe2), with a distorted 1T structure, exhibits a large magnetoresistance that depends on the orientation, and its electrical characteristics chan…
Raman Signatures of Polytypism in Molybdenum Disulfide
Jae-Ung Lee, Kangwon Kim, Songhee Han +3
Since the stacking order sensitively affects various physical properties of layered materials, accurate determination of the stacking order is important for studying the basic prop…
Anomalous polarization dependence of Raman scattering and crystallographic orientation of black phosphorus
Jungcheol Kim, Jae-Ung Lee, Jinhwan Lee +4
We investigated polarization dependence of the Raman modes in black phosphorus (BP) using five different excitation wavelengths. The crystallographic orientation was determined by…
