Mo2 W2 Se6 S2
semiconductor· Mo2 W2 Se6 S2
Mo₂W₂Se₆S₂ is a mixed-metal dichalcogenide semiconductor combining molybdenum, tungsten, selenium, and sulfur in a layered crystalline structure. This compound belongs to the family of transition metal dichalcogenides (TMDs), which are of significant research interest for next-generation optoelectronic and energy conversion devices. The material is primarily in experimental and developmental stages, with potential advantages over single-component TMDs (like MoS₂) due to band gap engineering and enhanced electronic properties achievable through elemental alloying.
