High Pressure Studies on n-Type Se±In±Pb Chalcogenide Glasses

چکیده
The measurement of dc conductivity as a function of pressure in the range 0 P < 2:0 GPa for Se75In25ÿxPbx (x 0, 5, 10, 15) glasses are reported. n-type Se±In±Pb glasses show a maximum in the resistance versus pressure. Differential Scanning Calorimetric (DSC) studies have also been carried out for the measurement of the glass transition temperature Tg. The results have been explained in terms of the presence of fourfold coordinated Pb atoms in the Se±In host matrix.

Microstructure, 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 structural and optical characterization of Se-Ge alloys during melt quenching technique was the goal of this study. In this regards, five different samples of Se100-xGex (x= 10, 20, 30, 40, 50) were prepared by conventional melt quenching in quartz ampoule. The produced samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calori...

Cu doped chalcogenide ChG glassy films in the As–Se–Te glass system have been prepared using thermal evaporation techniques. Single-source evaporation from bulk 1−x As0.40Se0.35Te0.25+x Cu glasses with x=0.05, 0.075, 0.10, 0.125, and 0.15, as well as dual-source coevaporation from As-chalcogenide and Cu-chalcogenide binary glasses as source materials, has been explored. We have shown that it is...
متن کاملSilver incorporation in Ge–Se glasses used in programmable metallization cell devices
We investigate the nature of thin films formed by the photodissolution of Ag into Se-rich Ge–Se glasses for use in programmable metallization cell devices. These devices rely on ion transport in the film so produced to create electrically programmable resistance states. The way in which Ag incorporates into the chalcogenide film during photodiffusion is examined using Rutherford backscattering ...
متن کاملOn the analogy between photoluminescence and carrier-type reversal in Bi- and Pb-doped glasses.
Reaction order in Bi-doped oxide glasses depends on the optical basicity of the glass host. Red and NIR photoluminescence (PL) bands result from Bi(2+) and Bin clusters, respectively. Very similar centers are present in Bi- and Pb-doped oxide and chalcogenide glasses. Bi-implanted and Bi melt-doped chalcogenide glasses display new PL bands, indicating that new Bi centers are formed. Bi-related ...
