Thermal annealing dependence of the structural, optical and electrical properties of selenium–tellerium films

Thermal annealing effect of on optical constants of vacuum evaporated Se75S25−xCdx chalcogenide thin films

“…Goksen et al [7] have studied the optical constants of Tl-Ga-In-Se layered single crystal. Soltan et al [8] have studied thermal annealing dependence of the structural, optical and electrical properties of selenium-tellerium films. The work on effect of annealing on optical band gap of amorphous Ga-Se-Sb during crystallization and effect of annealing on crystallization process in amorphous Ge-Se-Te thin films by Shamshad et al [9,10] are also worth mentioning.…”

Effect of SnI2 on the thermal and optical properties of Ge–Se–Te glasses

“…where The bonds are formed in the sequence of decreasing bond energies until all available valances for the atoms are saturated [16,17]. In Ge-Se-Te-SnI 2 glass system, the drop in the T g might be due to the formation of the weaker Te-Te and Sn-Te bonds and the reduction of the stronger Ge-Se and Se-Se bonds with the addition of SnI 2 to Ge-Se-Te glasses.…”

Analysis of composition dependence of some thermal transport properties in glassy Se80−xTe20Snx (0⩽x⩽10) alloys using transient plane source measurements

“…Chalcogenide materials have various technological applications in the areas of photonics and telecommunication [1][2][3][4][5][6][7][8][9]. These materials exhibit attractive electrical, optical and thermal properties which make them useful for several potential applications such as threshold switches, the production of copying machine and chip solar cells [3,4].…”

“…Analytically, these glasses are widely used as chemical and physical sensors in environmental monitoring and process control. Recently, the optical properties (like high refractive index, low phonon energy) are studied by various workers to search their practical utility in fabrication of active devices in fiber-optics as well as in laser-optics [5][6][7][8][9]. a-Se-Te alloys have gained much importance due to their higher photosensitivity, crystallization temperature, hardness and smaller aging effects [10,11] as compared to a-Se.…”
