Abstract

This article identifies a length scale for spinodal decomposition of Hf and Zr silicate alloys. This has provided important insights into chemical bonding self‐organizations in non‐crystalline alloys as well, in particular for the intermediate phase regime of chalcogenide alloys. Additional insights into nanolength scales for chemical bonding self‐organizations; also extending into the medium range order (MRO) regime in network glasses are identified through comparisons between the first sharp diffraction peaks in oxide and chalcogenide compounds and alloys. These length scales are based on the extraction of real space correlation and coherence lengths, R and L, respectively. These comparisons have identified bond‐ionicity related differences in the short range order which play a significant role in promoting differences in MRO between oxides and chalcogenides, including bulk glasses as well as thin films.
