چکیده
Using Messbauer spectroscopy on 119 Sn impurity atoms, it was demonstrated that in amorphous (GeTe) x (Sb 2 Te 3 ) films (where x=0.5, 1, 2, 3) tin atoms replace of tetravalent germanium, which forms a tetrahedral system chemical bonds with its local environment. In crystalline films, replaces divalent six-coordinated germanium positions 4b the NaCl-type crystal lattice. Keywords: phase memory, spectroscopy.

Toward the Ultimate Limit of Phase Change in Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub>
The limit to which the phase change memory material Ge2Sb2Te5 can be scaled toward the smallest possible memory cell is investigated using structural and optical methodologies. The encapsulation material surrounding the Ge2Sb2Te5 has an increasingly dominant effect on the material’s ability to change phase, and a profound increase in the crystallization temperature is observed when the Ge2Sb2Te...

Topological insulators exhibit a bulk energy gap and spin-polarized surface states that lead to unique electronic properties1–9, with potential applications in spintronics and quantum information processing. However, transport measurements have typically been dominated by residual bulk charge carriers originating from crystal defects or environmental doping10–12, and these mask the contribution...
متن کاملInherent Simple Cubic Lattice Being Responsible for Ultrafast Solid-Phase Change of Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub>
Crystallization of solid is generally slow in kinetics for atoms trapped in solids. Phase-change materials (PCMs) challenge current theory on its ultrafast reversible amorphous-to-crystal transition. Here by using the stochastic surface walking global optimization method, we establish the first global potential energy surface (PES) for Ge2Sb2Te5. By analyzing all structures on the global PES, w...

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
