Octahedral to tetrahedral bonding transitions in the local structure of phase change optical media Ge2Sb2Se5xTe5−5x with Se doping
Random access memories utilize fast, reversible switching between ordered and disordered states of matter in phase change materials (PCMs) such as Ge2Sb2Te5−5x. The short-range structure in the disordered phase has been described either as (i) a network of Ge tetrahedra or (ii) Peierls distorted Ge/...
