We have investigated the electronic structures of single- and double-layered MoS${}_{2}$, composing heterojunction such as graphene, SiO${}_{2}$ MoS${}_{2}$ SiO${}_{2}$, using scanning photoelectron microscopy. Negative shifts both core levels valence bands toward Fermi energy been observed. In connection with first-principles calculations, we confirmed that direct gap single-layer is changed to an indirect by stacking additional layers via van der Waals interlayer interactions.
The electronic structure of superoxide ${\text{KO}}_{2}$ was investigated by employing soft x-ray absorption spectroscopy (XAS) and core-level photoemission (PES). clean single component observed in both the $\text{O}\text{ }1s$ $\text{K}\text{ }2p$ PES spectra ${\text{KO}}_{2}$, which confirms good quality sample employed this work. measured XAS spectrum compared with calculated density states (DOSs), obtained from first-principles electronic-structure calculations that include spin-orbit...

Electronic structures of perovskite oxides SrMn${}_{1\ensuremath{-}x}$Mo${}_{x}$O${}_{3}$ in the Mo-rich regime ($x\ensuremath{\geqslant}0.5$) have been investigated by employing soft x-ray absorption spectroscopy (XAS). Mn $2p$ XAS spectra indicate that valence states ions are divalent and they remain nearly unchanged for $x\ensuremath{\geqslant}0.5$. On other hand, Mo $3p$ show some changes, suggesting decrease with increasing $x$ These conclusions supported unoccupied $3d$ $4d$ states,...
The objective of this study was to determine whether severity and change coexisting psychiatric symptoms might affect complicated grief (CG) regarding the Sewol ferry disaster.Data from a cross-sectional survey were obtained 18 months (Time 1) 30 2) after disaster. We ascertained sociodemographic variables self-reporting questionnaires (i.e., CG, depression, anxiety, post-traumatic stress disorder [PTSD], insomnia, embitterment, suicidal risk) among 56 bereaved family members.Severity other...
Electronic structures of Ni-doped CuFe1-xNixO2 delafossite oxides (x = 0, 0.015, and 0.03) have been investigated by employing soft x-ray absorption spectroscopy magnetic circular dichroism (XMCD). It is found that the valence states Cu, Fe, Ni ions are nearly monovalent (Cu+), trivalent (Fe3+), divalent (Ni2+), respectively, they do not change with x. In contrast, Cu 2p XMCD signals, which arise from Cu2+ states, increase increasing This study suggests signals presumably related to...
Objective Infertility, the inability to achieve pregnancy within a year despite normal attempts conceive without contraception, causes psychosocial burden for individuals and couples. This review summarized interrelationship between infertility psychological stress suggested various forms of intervention infertility.Methods The PubMed, Google Scholar, Korean Studies Information Service System databases were searched English- Korean-language articles published from 1990 2024.Results...
This study attempted to grasp the reality of hierarchical patriarchy through violent discipline and its glorification process, focusing on Korean long-form novels, “Hyŏnssiyangungssangnin’gi” “Hyŏnmongssangnyonggi”, in which ideal patriarchs appear. The physical punishment parents has been affirmed as a hawk love. Considering that there is still perception affirms today, it natural corporal was accepted naturally during Joseon Dynasty. In both texts, considered legitimate suitable for...
X-irradiation of Ph3AsF2 single crystals produces a radical exhibiting hyperfine coupling with one 75As nucleus and two 19F nuclei. The three tensors are determined show that the unpaired electron is delocalized in 4s (17%) 4p (55%) arsenic orbitals 2p (∼12%) orbital each fluorine atom. ESR parameters consistent either Ph2AsF2 or Ph3AsF−2 but theoretical estimates geometry these species together experimental angle 135° between principal axes more accord structure Ph3AsF−2.
Electronic structures of a charge-density-wave CDW system CeTe_2-xSb_x (x=0, 0.05) have been investigated by employing angle-resolved photoemission spectroscopy (ARPES). The observed Fermi surface (FS) agrees very well with the calculated FS for undistorted CeTe_2 both in shapes and sizes. metallic states crossing level(E_F) are ARPES. carriers near E_F mainly Te(1) 5p character, negligible contribution from Ce 4f to formation. supercell (shadow) bands corresponding weak FS's found arise...
Electronic structures of perovskite oxides SrMn1-xMoxO3 (0 ≤x≤ 0.75) have been investigated by employing soft x-ray absorption spectroscopy (XAS) and photoemission (PES). It is found that the valence states Mn ions change systematically from Mn4+ for x = 0, to nearly Mn3+ 0.3, Mn2+ 0.5, then remain as x≥0.5. Both Mo 3d core-level PES 3p XAS spectra show unchanged being hexavalent (Mo6+) x≤0.5 but they decrease x>0.5 with increasing x. This study shows are mixed-valent in SrMn1-xMoxO3,...
