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…
Antiferromagnetic ordering in van der Waals two-dimensional magnetic material MnPS3 probed by Raman spectroscopy
Kangwon Kim, Soo Yeon Lim, Jungcheol Kim +8
Magnetic ordering in the two-dimensional limit has been one of the most important issues in condensed matter physics for the past several decades. The recent discovery of new magne…
Suppression of magnetic ordering in XXZ-type antiferromagnetic monolayer NiPS3
Kangwon Kim, Soo Yeon Lim, Jae-Ung Lee +7
How a certain ground state of complex physical systems emerges, especially in two-dimensional materials, is a fundamental question in condensed-matter physics. A particularly inter…
Strain-shear coupling in bilayer MoS2
Jae-Ung Lee, Sungjong Woo, Jaesung Park +3
Layered materials such as graphite and transition metal dichalcogenides have extremely anisotropic mechanical properties owing to orders of magnitude difference between in-plane an…
Excitation energy dependence of Raman spectra of few-layer WS2
Jinho Yang, Jae-Ung Lee, Hyeonsik Cheong
Raman spectra of few-layer WS2 have been measured with up to seven excitation energies, and peculiar resonance effects are observed. The two-phonon acoustic phonon scattering signa…
Anomalous excitonic resonance Raman effects in few-layer MoS2
Jae-Ung Lee, Jaesung Park, Young-Woo Son +1
The resonance effects on the Raman spectra from 5 to 900 cm-1 of few-layer MoS2 thin films up to 14-layers were investigated by using six excitation energies. For the main first-or…
