Structure of amorphous and glassy Sb2S3 and its connection with the structure of As2X3 arsenic chalcogenide glasses

121Sb Mössbauer Study of Sb2S3–As2S3–Tl2S Glasses

“…In agreement with the study of Cervinka and Hruby (32), we demonstrated the existence of weak bonds around 3.0 A > in the antimony environments. This present study confirms that the sequence of pyramidal coordination patterns leads to the gradual transition from layer-like to a random network in this system.…”

“…These weak bonds provide the cohesion between the successive layers. Cervinka and Hruby (32) have constructed a simple model of vitreous Sb S . In this model the explanation of the non-zero electron density of the radial electron density distribution curve in the region of 3 A > , was achieved by a suitable mutual orientation of elementary SbS E units shown in Fig.…”

Experimental Studies on Ge–S–Ag Glasses

“…This type of connection between the IRO and the thermal stability of the glass, observed in this work, was reported for As±Se glasses [43] where the inhibition of crystallization ability is accompanied by the growth of a FSDP. It was also reported for the excellent glass-former B 2 O 3 [29] for which the FSDP is the strongest peak in the diffraction pattern, for the poor glass-former Sb 2 S 3 [44] which exhibits a small FSDP in its diffraction pattern, and for Ge±Se [45], a very poor glassformer, where the FSDP is virtually eliminated.…”

STRUCTURAL CHARACTERIZATION AND ELECTRICAL PROPERTIES OF a- S/Sb RATIO THIN FILMS.

“…At Z=2.4, the layer structure is fully developed, exhibiting the maximal diffraction peak intensity, which decreases further with increasing the number of cross-linked sites [16]. The peak value of 2θ=40º is the shortest distance between Sb-S atoms suggesting the triple pyramid, Sb 2 S 3, units represent the basic building block of the network structure [17]. The grain size of the peak around 2θ=40º (Sb 2 S 3 phase) was calculated from XRD patterns by using Deby-Scherrer's formula; L=0.9λ/Bcosθ, where, B is the full-width at half-maximum (FWHM).…”
