Segregation-induced Ge precipitation in Ge2Sb2Te5 and N-doped Ge2Sb2Te5 line cells

Electromigration in Ge2Sb2Te5 and N-doped Ge2Sb2Te5 line cell structures has been studied by mapping out electric field/current-induced composition changes using x-ray energy dispersive spectroscopy. Both materials exhibit pronounced segregation in a molten state, with Te moving toward the anode and...
