“…The coexistence of the ferroelectric and paraelectric phases of bulk SbSI near the Curie point was discussed in (Starczewska et al, 2009). From the differences in XRD data, it was concluded (Starczewska et al, 2009) ; b) -after (Starczewska et al, 2009) All diffraction peaks in XRD pattern of sonochemical prepared SbSeI (Nowak et al, 2009b) were indexed to be a pure orthorhombic phase for SbSeI with the cell constants a=0.86862 (9) nm, b=1.0.3927(3) nm, and c=0.41452(9) nm very close to the data reported for bulk SbSeI www.intechopen.com crystals (Voutsas & Rentzeperis, 1982). However, the XRD patterns ( Fig.…”

“…It contains double chains [(SbSeI) ∞ ] 2 consisting of two chains (SbSeI) ∞ related by a two-fold screw axis and linked together by short and strong Sb-Se bonds [6,8]. Weak van der Waals-type bonds of d > 3.8Å (bond strength 0.06) bind the double chains.…”

The paper presents the X-ray photoelectron spectra (XPS) of the valence band (VB) and of the principal core levels from the (110) and (001) crystal surfaces for the quasi-one-dimensional high permittivity SbSeI single crystal isostructural to ferroelectric SbSI. The XPS were measured with monochromatized Al Ka radiation in the energy range of 0-1400 eV at room temperature. The VB is located from 1.6 to 20 eV below the Fermi level. Experimental energies of the VB and core levels are compared with the results of theoretical ab initio calculations of the molecular model of the SbSeI crystal. The electronic structure of the VB is revealed. Shifts in the core-level binding energies of surface atoms relative to bulk ones, which show a dependency on surface crystallography, have been observed. The chemical shifts of the core levels (CL) in the SbSeI crystal for the Sb, I and Se states are obtained.

“…SbSeI belongs to the 1:1:1 compounds and crystallizes in the SbSI structure type (Fig. 1), space group Pnma, with the unit cell parameters a = 8.6862 (9), b = 10.3927 (9), c = 4.1452(3) Å [4]. In its crystal structure, antimony and selenium form double chains spreading along the "c" direction of the unit cell.…”
