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…

Origin of ferroelectric-like hysteresis loop of CaCu3Ti4O12 ceramic studied by impedance and micro-Raman spectroscopy
Sungmin Park, Hyosang Kwon, Doyoung Park +2
Ferroelectric-like hysteresis loops of CaCu3Ti4O12 (CCTO) ceramic have been observed. We found that this unusual feature does not arise from the displacement of the Ti ions in the…
