· Te4 As4 Ru4

Te₄As₄Ru₄ is a mixed-valence quaternary compound combining tellurium, arsenic, and ruthenium in a stoichiometric ratio, belonging to the chalcogenide semiconductor family with potential for advanced electronic and photonic applications. This is a research-phase material rather than an established commercial compound; compounds in this composition space are investigated for their electronic band structures, thermoelectric properties, and possible topological characteristics that could enable next-generation energy conversion or quantum devices. The ruthenium incorporation and mixed-chalcogen framework distinguish it from conventional binary or ternary semiconductors, making it of interest to materials chemists exploring novel intermetallic-chalcogenide hybrids.
