Toward the Ultimate Limit of Phase Change in Ge₂Sb₂Te₅

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...

Magnetic properties of the Haldane-gap material [Ni(C₂H₈N₂)₂NO₂](BF₄)

Results of magnetization and high-field electron spin resonance (ESR) studies of the new spin-1 Haldane-chain material [Ni(C2H8N2)2NO2] (BF4) (NENB) are reported. A definite signature of the Haldane state in NENB was obtained. From the analysis of the frequency–field dependence of magnetic excitations in NENB, the spin-Hamiltonian parameters were calculated, yielding 1/kB = 17.4 K, g‖ = 2.14, D...

Effect of Rb and Ta Doping on the Ionic Conductivity and Stability of the Garnet Li_{7+2<italic>x</italic><italic>y</italic>}(La_{3<italic>x</italic>}Rb_{<italic>x</italic>})(Zr_{2<italic>y</italic>}Ta_{<italic>y</italic>})O₁₂ (0 <italic>x</italic> 0.375, 0 <italic>y</italic> 1) Superionic Conductor: A First Principles Investigation

In this work, we investigated the effect of Rb and Ta doping on the ionic conductivity and stability of the garnet Li7+2x−y(La3−xRbx)(Zr2−yTay)O12 (0 ≤ x ≤ 0.375, 0 ≤ y ≤ 1) superionic conductor using first principles calculations. Our results indicate that doping does not greatly alter the topology of the migration pathway, but instead acts primarily to change the lithium concentration. The st...
