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…
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…
Ising-Type Magnetic Ordering in Atomically Thin FePS3
Jae-Ung Lee, Sungmin Lee, Ji Hoon Ryoo +6
Magnetism in two-dimensional materials is not only of fundamental scientific interest but also a promising candidate for numerous applications. However, studies so far, especially…
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…
