TL;DR: In this article, the authors measured the viscosity of selenium by using three different methods; the penetration method, the parallel-plate method and the rotating bob method, and the temperature dependence of all these results are expressed by the Adam-Gibbs (AG) and the Vogel-Fulcher-Tamman (VFT) equations.

TL;DR: Chalcogenide glass-formers are being used in a remarkable range of various optoelectronic, photonics, photoconducting, sensing and memory device applications.

TL;DR: In this paper, the authors measured the viscosity of supercooled melts by penetration and parallel-plate methods as a function of temperature and found that the visco-temperature dependence of viscosities can be expressed by a simple equation of Arrhenius type.

TL;DR: The experimental growth data were combined with melting and viscosity data and the appropriate growth models were proposed to describe crystal growth in a wide temperature region to provide better description of experimental data and more realistic value of the parameter describing the mean interatomic distance in the crystal-liquid interface layer, where the crystal growth takes place.

TL;DR: In this paper, the authors measured the viscosity of the whole measurable region of undercooled melt and of the part of glass region using parallel-plate method and penetration method, and calculated the kinetic fragilities calculated from these dependencies with similar compositional dependence as heat capacity changes at glass transition measured by DSC.
