In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se85-xTe15Sbx (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of ...
Semiconductor chalcogenide glasses are used in a wide range of applications as solid-state devices, both in scientific and technological fields. In this article, the mechanism of degradation of these materials is studied. The technique was used to measure the variation of thermal conductivity and thermal diffusivity of samples with different exposure times to neutron irradiation. Thermal conductivity and diffusivity increases proportionally with smaller exposure time, while at higher exposure times ...
Using the transient plane source (TPS) technique, simultaneous measurements of thermal conductivity and thermal diffusivity were taken from phenolformaldehyde (PF) composites, reinforced by pineapple leaf fiber. Testing was done on samples of varying weight percentages. Thermal conductivity of pure fiber was evaluated and compared with the thermal conductivity of the composite fiber....
A chalcogenide glass was prepared and doped with carbon nanotubes (CNTs) in an effort to increase the electrical and thermal conductivity of the glass. The glass that was used in this study was Se85Te10Ag5 which was prepared by melt-quenched method. CNTs were added to the glass at 3 and 5 wt. % and the properties of the composite glasses were compared with those of the pure chalcogenide glass. It was found ...
Zn-Se alloys have potential applications in blue light emitting diodes and blue diode lasers, as well as in white LEDs and infrared lenses. Se-In alloys have potential applications in solar cells due to their energy band gap, which is close to the optimum range for solar energy conversion. The thermo-physical properties of these two types of alloys have been investigated to further their applicability in industrial applications. The thermal conductivity, ...
