· JVASP-10227· TlPS3

TlPS₃ is a layered ternary chalcogenide ceramic compound consisting of thallium and phosphorus sulfide, belonging to the family of van der Waals materials with anisotropic crystal structure. This material is primarily investigated in condensed matter physics and materials research for its unique electronic and vibrational properties rather than established commercial applications. Its potential relevance stems from emerging interest in two-dimensional materials and heterostructures for optoelectronic and quantum device applications, though it remains largely in the research phase without widespread industrial adoption.
