Usable electric current can be synthesized from photo electrochemical cells. The unit cells are group together to form a series of solar panel. The arrays of solar panel are generally placed under glass, polymer or plastic as a protection from the weather [1]. The usage of transition metal chalcogenide thin film in solar energy conversion can lead to a good path in developing a bright future fo...

Chalcogenide glasses are amorphous solid materials formed from chalcogen elements bonding with metals to form typically in binary or tertiary compounds. One family of chalcogenide glasses, based on gallium and lanthanum sulphides, possesses properties important for the infrared (IR) window transmissions IR applications; these include thermal stability, high solubility rare earth ions, low phono...

The temperature dependence of the viscosity inorganic glasses in glass transition region is successfully described by Williams--Landel--Ferry (WLF) equation. For studied glasses, value f_g=1/C 1 weakly depends on nature glasses. There a linear correlation between delta T g and . From data parameters WLF equation C 2 , we calculated as well relaxation time structure tau at under study. Keywords:...

An etch-free and cost-effective deposition and patterning method to fabricate mid-infrared chalcogenide glass waveguides for chemical sensing applications is introduced. As(2)S(3) raised strip optical waveguides are produced by casting a liquid solution of As(2)S(3) glass in capillary channel molds formed by soft lithography. Mid-IR transmission is characterized by coupling the output of a quan...

Multimaterial optical fibers combining tellurite with chalcogenide glasses and featuring thin polymer structures are fabricated via the thermal drawing process. It is demonstrated that micrometric polyethersulfone films can be embedded within larger elongated tellurite/chalcogenide glass architectures. Taking advantage of strong chemical reactivity contrasts which exist in considered fiber geom...

Electrical switching in germanium telluride glasses containing metallic atoms (Cu and Ag) has been investigated. All these glasses are found to exhibit memory switching. The switching fields of these glasses are compared with the thermal parameters evaluated from DSC studies and the results are explained on the basis of the thermal model. The composition dependence of the switching field and th...
