Dielectric and structural characterisation of chalcogenide glasses via terahertz time-domain spectroscopy
نویسندگان
چکیده
Terahertz time-domain spectroscopy (THz TDS) was used to investigate a series of chalcogenide glasses. In particular, the dielectric properties at terahertz frequencies were determined and correlated with the glass composition. The experimental results showed a strong relationship between the dielectric properties and the polarizability of the glasses studied. A new explanation based on the coordination number of the metallic cations was proposed to understand these observations. © 2017 Published by Elsevier B.V.

متن کاملMicrostructure, mechanical and thermal properties of chalcogenide glasses and glass-ceramics based on Se-As-Ge system nucleated by Sn
In particular, chalcogenide glasses and glass-ceramics are new materials that exhibit good transparency in infrared region (0.8-12µm). We can overcome the main weakness of these glasses by improving the hardness through controlling crystallization. In this paper, we report results of a study on chalcogenide glasses in the ternary system of As-Se-Ge with nominal composition of Snx (Se...

The band structure of two-dimensional chalcogenide glass photonic crystal of triangular lattice structure is calculated at terahertz frequencies using Plane Wave Expansion Method. The band gap ratio was found to vary with variation of the structural parameters such as fill factor and dielectric contrast. The spatial asymmetry associated with lattice structure gives rise to a complete photonic b...
متن کاملBeating the wavelength limit: three-dimensional imaging of buried subwavelength fractures in sculpture and construction materials by terahertz time-domain reflection spectroscopy.
We use reflection terahertz spectroscopy to locate and produce three-dimensional images of air gaps between stones that resemble fractures, even of subwavelength thicknesses. This technique is found to be promising tool for sculpture and building damage evaluation as well as structural quality control in other dielectric materials.
