X-ray absorption study of the GeSe system

Intermediate-range order in glassy GexSe1−x around the stiffness transition composition

“…Therefore, precise studies of the concentration dependence of the atomic structure of glassy Ge x Se 1Àx were performed using this technique in the concentration range 0 6 x 6 0:333 [11][12][13]. The experiments confirmed the predicted coordination numbers (8 À N rule) with a bond length similar to that in the crystal.…”

Short-Range Order in Se-Rich Ge–Se Glasses—An Extended X-Ray Absorption Fine Structure Study

“…No raw data were shown; hence, the quality of these data are uncertain. In contrast to Zhou et al (2), Peyroutou et al (19,20) were able to resolve both the "rst and the second coordination sphere for their vitreous samples. The Debye}Waller factors reported are anomalously low.…”

“…The shortest Ge}Se bond length reported by Zhou et al (2) for glassy GeSe is, however, slightly long compared to that in the crystal and that reported in the present work. EXAFS data of Ge}Se alloys have also been reported by Peyroutou et al (19,20). No raw data were shown; hence, the quality of these data are uncertain.…”

“…The coordination number obtained by Zhou et al (2) for vitreous Se, 1.8$0.2, is larger than that obtained in the present study. Low coordination numbers for Se were observed by Peyroutou et al (19,20).…”

Morphology and structural studies of Ag photo-diffused GeySe1−y thin films prepared by RF-sputtering

“…have been used quite extensively in order to analyze the structural and thermal stability, the photosensitivity, etc. [7][8][9][10][11][12][13][14].…”
