Structural Phase Transition and Interlayer Coupling in Few-Layer 1T' and Td MoTe2
Yeryun Cheon, Soo Yeon Lim, Kangwon Kim +1
We performed polarized Raman spectroscopy on mechanically exfoliated few-layer MoTe2 samples and observed both 1T' and Td phases at room temperature. Few-layer 1T' and Td MoTe2 exh…
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…
Variation of photoluminescence spectral line shape of monolayer WS2
Yongjae Kwon, Kangwon Kim, Wontaek Kim +2
The origin of the variation of photoluminescence (PL) spectra of monolayer tungsten disulfide (WS2) is investigated systematically. Dependence of the PL spectrum on the excitation…
Excitonic Resonance Effects and Davydov Splitting in Circularly Polarized Raman Spectra of Few-Layer WSe2
Sanghun Kim, Kangwon Kim, Jae-Ung Lee +1
Few-layer tungsten diselenide (WSe2) is investigated using circularly polarized Raman spectroscopy with up to eight excitation energies. The main E2g1 and A1g modes near 250 cm-1 a…
Davydov splitting and excitonic resonance effects in Raman spectra of few-Layer MoSe2
Kangwon Kim, Jae-Ung Lee, Dahyun Nam +1
Raman spectra of few-layer MoSe2 were measured with 8 excitation energies. New peaks that appear only near resonance with various exciton states are analyzed, and the modes are ass…
Resonant Raman and photoluminescence spectra of suspended molybdenum disulfide
Jae-Ung Lee, Kangwon Kim, Hyeonsik Cheong
Raman and photoluminescence (PL) measurements were performed on suspended and supported MoS2 up to 6 trilayers (TLs). The difference in the dielectric environment of suspended and…
