Models of the amorphous phase of GeSbTe have been generated by density functional molecular dynamics simulations with the Becke–Lee–Yang–Parr (BLYP) exchange–correlation functional. Four independent 459-atom models have been used to improve t

We studied the epitaxial TiN(001)/Ge2Sb2Te5(001) (GST) interface of interest for applications in phase change non-volatile memories by means of density functional calculations. The cubic phase of GST of interest for the memory devices was considered.

The line shape of the Auger decay of adatoms is studied by a joint theoretical and experimental effort, the former within a DFT framework, and the latter with synchrotron radiation measurements. We investigate the $K{L}_{2,3}V$ Auger deexcitation of
