Journal ArticleDOI
Characterization of supercooled liquid Ge2Sb2Te5 and its crystallization by ultrafast-heating calorimetry
TL;DR: Differential scanning calorimetry (DSC) is widely used to study the stability of amorphous solids, characterizing the kinetics of crystallization close to the glass-transition temperature Tg as discussed by the authors.
Journal ArticleDOI
Fragile‐to‐Strong Crossover in Supercooled Liquid Ag‐In‐Sb‐Te Studied by Ultrafast Calorimetry
TL;DR: In this article, the authors used ultrafast-heating calorimetry to explore the temperature dependence for the growth-dominated medium Ag-In-Sb-Te.
Journal ArticleDOI
Fast and slow crystal growth kinetics in glass-forming melts
Jiri Orava,A.L. Greer +1 more
TL;DR: Despite the difference of more than 11 orders of magnitude in U(max) seen in pure metals and in silica, the range of glass-forming systems surveyed fit into a common pattern in which the lability increases with lower reduced glass-transition temperature (T(g)/T(m)) and higher fragility of the liquid.
Journal ArticleDOI
Optical properties and phase change transition in Ge2Sb2Te5 flash evaporated thin films studied by temperature dependent spectroscopic ellipsometry
TL;DR: In this article, the optical properties of as-prepared (amorphous) and thermally crystallized (fcc) flash evaporated Ge2Sb2Te5 thin films using variable angle spectroscopic ellipsometry in the photon energy range 0.54-4.13 eV.
Journal ArticleDOI

TL;DR: In this article, the influence of cryothermal treatment on the mechanical properties of metallic glasses with different compositions was investigated, and it was found that cryothermal cycling can induce rejuvenation as well as relaxation of the metallic glasses.
