Y2 Ag2 Se4
semiconductor· Y2 Ag2 Se4
Y2Ag2Se4 is a ternary semiconductor compound combining yttrium, silver, and selenium, belonging to the family of mixed-metal chalcogenides. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its layered structure and mixed-valence composition offer potential for tunable electronic properties and efficient charge carrier transport. The incorporation of silver and selenium creates an anisotropic crystal structure that may enable enhanced performance in niche applications where conventional binary semiconductors are limiting.
