Quasiparticle band structures, spontaneous polarization, and spin-splitting in noncentrosymmetric few-layer and bulk -GeSe
Han-gyu Kim, Hyoung Joon Choi
Group-IV monochalcogenides have attracted much attention due to their potential of ferroelectric and multiferroic properties. Recently, centrosymmetric gamma-phase GeSe in a double…
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…
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…
Enhanced electrocatalytic activity via phase transitions in strongly correlated SrRuO3 thin films
Sang A Lee, Seokjae Oh, Jae-Yeol Hwang +12
Transition metal oxides have been extensively studied and utilized as efficient catalysts. However, the strongly correlated behavior which often results in intriguing emergent phen…
