ChemInform Abstract: ELEKTRONOGRAPHISCHE UNTERSUCHUNG DER STRUKTUR VON AMORPHEN NI3GE‐FILMEN

Low-Temperature Preparation of High-Temperature Nickel Germanides Using Multilayer Reactants

“…Indeed, electron diffraction studies of co-sputtered NiGe films with comparable composition suggest the structure of the amorphous phase closely resembles the structure of crystalline -Ni 5 Ge 3 . 20 This line of reasoning proves compelling for a general explanation of our results, in that the three hightemperature phases accessible by our synthetic technique are structurally related. The structures of Ni 3 Ge 2 , Ni 5 Ge 3 , and δ-Ni 5 Ge 2 are all derived from the prototype NiAs structure, consisting of alternating close-packed sheets.…”

“…The preferential formation of ε-Ni 5 Ge 3 , therefore, is indicative of a close structural similarity between the amorphous NiGe and the crystalline product. Indeed, electron diffraction studies of co-sputtered NiGe films with comparable composition suggest the structure of the amorphous phase closely resembles the structure of crystalline ε-Ni 5 Ge 3 3 (110) projections of NiAs-derived structures of various nickel germanide phases of (a) NiAs prototype, (b) InNi 2 prototype, and (c) Pd 5 Sb 2 prototype.…”
