Organic-inorganic hybrid metal halides (OIMHs) are emerging functional materials with diverse applications. However, the exploration of mechanically soft OIMHs remains limited. This study introduces tin(IV) OIMH crystals ( 1 and 1w ),...
The valence-band photoemission of Ni(110) shows that the two-hole satellite appears at a constant binding energy 6.0 eV away from 3p\ensuremath{\rightarrow}3d resonance in accord with earlier results, but on it shifts to \ensuremath{\sim}6.8 eV. Interpretation this new result terms singlet and triplet states is proposed.
The photon-energy dependence of the angle-resolved photoemission Fe(110) has been measured to investigate existence a valence-band satellite. Contrary earlier observation satellite at about 6 eV below Fermi edge, no feature is found in spectra on clean surface, even for excitations around 3p threshold. In after exposing surface oxygen, appears eV. Such an oxygen-induced could spuriously be regarded as plot intensity main 3d band versus excitation energy shows profile with only dip near...

The photon-energy (h\ensuremath{\nu}) dependence of the angle-integrated and angle-resolved photoemission from Ni(110) has been measured to investigate valence-band satellite. Contrary earlier observations, we found that satellite moves with h\ensuremath{\nu}. centroid is observed at \ensuremath{\sim}6.0 eV below Fermi energy (${E}_{F}$), away 3p-3d resonance, \ensuremath{\sim}6.8 in region resonance. difference spectra show on resonance highest-binding-energy part (at \ensuremath{\sim}7.3...
People-centered risk communication is important to mitigate the flood damage caused by recent increase in heavy rainfall events Japan. Longitudinal studies are particularly for evaluating effectiveness of methods; however, current research insufficient. To address this gap, we conducted a longitudinal study, specifically through four panel surveys over short period, investigate effects various methods such as running an evacuation simulation learn about damage, providing information behavior...
Rare-gas metastable atoms (${\mathrm{He}}^{\mathrm{*}}$,${\mathrm{Ne}}^{\mathrm{*}}$,${\mathrm{Ar}}^{\mathrm{*}}$) were shown to deexcite on a graphite surface via the direct Auger deexcitation process. This is first observed case in which resonance ionization of suppressed with empty levels having same energy as those highest occupied atoms. The electron emission spectra correlate closely density-of-states maxima originating from \ensuremath{\pi} bands, while contribution...
The electronic properties of a thin FeO(111) layer epitaxially grown on Fe(110) have been studied by angle-resolved photoemission spectroscopy using polarized synchrotron radiation. normal-emission spectra show five features: Fe 3d--derived states at \ensuremath{\sim}0.4 and 2.7 eV below the Fermi energy, O 2p--derived \ensuremath{\sim}4.1 \ensuremath{\sim}6.0 eV, multielectron satellite feature 11.5 eV. binding energies these were independent h\ensuremath{\nu} within...
A combined spectroscopic and theoretical study has been performed to clarify the local electronic properties induced at C60-Pt(111) interface. The C60 molecules are regularly bound Pt(111) substrate via covalent bond, forming hybridized states just below Fermi level (EF). Such a metallic feature is originated by strong Pt 5d-C60 π couplings extended entire molecule, indicating that adsorbed molecule serves as an excellent mediator of metal wave function. Our findings correspond well...
The electron emission spectrum resulting from thermal collisions of ${\mathrm{He}}^{\mathrm{*}}$(${2}^{3}$S) atoms with ${\mathrm{LaCoO}}_{3}$ was measured as well the h\ensuremath{\nu}-dependent photoemission spectra. ${\mathrm{He}}^{\mathrm{*}}$ shows that lower-lying Co 3d derived (main) bands are strongly suppressed relative to O 2p bands, reflecting spatial distribution initial wave functions. On other hand, higher-lying (satellite) band is anomalously enhanced in spectrum. These...
Electron emission spectra resulting from thermal collisions of He*(23S) metastable atoms with alkanethiols (CnH2n+1SH, n = 1−3) on a Pt(111) surface were measured to clarify the electronic properties induced at molecule−metal interface. Upon chemisorption, S 3p-derived states are broadened significantly by admixture Pt bands, yielding sharp Fermi edge, whereas such metallic state is missing in weakly bound species. The spectral feature agreement first-principles calculations using density...
We show that the 5.5-eV feature in photoemission spectra of Fe should not be assigned to a valence-band satellite.Received 25 July 1986DOI:https://doi.org/10.1103/PhysRevB.34.8973©1986 American Physical Society
A low energy electron microscope (LEEM) with an analyzer of the Wien filter type was constructed for surface microanalyses and imaging by irradiating specimen several types incident beams, e.g. electrons, UV photons or metastable He * atoms. retarding used formation filtered images spectra selected microareas employing loss Auger electron, photoelectron Penning ionization spectroscopy. Several new designs performances have been implemented in this instrument are presented together some applications.
The rotational isomerism of 1,2-dichloroethane (DCE, CH2ClCH2Cl) adsorbed on Pt(111) was studied in the temperature range 35-100 K using high-resolution electron energy loss spectroscopy and metastable atom spectroscopy. In coverage below monolayer physisorbed chemisorbed species coexist at 35 gauche slightly distorted trans form, respectively. Owing to direct Pt-Cl interactions, nonbonding Cl 3p states DCE are split off, giving rise degradation symmetry from pure form (C2h). conformers...
Electron emission spectra obtained by thermal collisions of He*(2 3S) metastable atoms with CO on Ni(100) in the c(2×2) structure and Ni(111) c(4×2) were measured to probe directly spatial electron distribution. For a systematic comparison, free CO, condensed Ni(111), gaseous Cr(CO)6 also under same beam conditions. Our data showed that relative ionization cross sections for 4σ-, 1π-, 5σ-derived states depend drastically molecular orientation respect beam, reflecting local density impact...
