Waveguide writing using a train of femtosecond laser pulses at 850 nm, in the transparent
spectral region of bulk As40S60 glasses is reported. Waveguides were written by translating …

Three elastic phases of covalent networks,(I) floppy,(II) isostatically rigid, and (III) stressed-
rigid, have now been identified in glasses at specific degrees of cross linking (or chemical …

Nanoscale phase separation effects are of general interest in glass science. Such structural
effects produce usually pronounced changes in glass physical properties which can mask …

We report structure-terahertz (THz) property relationship for various non-oxide chalcogenide
glasses including unary (vitreous selenium (Se)), binary (arsenic sulfide (As-S), arsenic …

This work is focused on the compositional dependencies in the Raman spectra of
amorphous Ge-As-Se and Ge-Sb-Te chalcogenides with the systematic increase of the Ge …

The structure of homogeneous bulk As x S100− x (25≤ x≤ 42) glasses, prepared by the
conventional rocking–melting–quenching method, was investigated using high-resolution X …

Melt dynamics and glass Topological phases of especially dry and homogenized binary
AsxS100− x melts/glasses are examined in Modulated-DSC, Raman scattering, and …

We here present ab initio calculations on small AsnSm clusters that are building blocks for
the formation of continuous random networks (CRN) generally found in AsxS100-x glasses …

Structural order in the chalcogenide glasses of (As 2 S 3) x (GeS 2) 1− x (x= 0.0, 0.1, 0.2, 0.4,
0.6, 0.8, 1.0) system is examined in terms of the parameters of local atomic structure as a …

Engineering new chalcogenide solids improves the desired functionality of the materials and
may open the way for new applications. Here we discuss the preparation of As x S 100− x …
