Here, we attempt to address all these questions by thoroughly investigating all types of structural units in various amorphous material systems, including amorphous monatomic chalcogens, binary tellurides, and ternary chalcogenides with different chalcogen elements. Surprisingly, it is shown that hypervalent...
