· JVASP-28402· MoWSe4

MoWSe₄ is a mixed-metal chalcogenide compound containing molybdenum, tungsten, and selenium—a ternary layered material that falls within the family of transition metal dichalcogenides (TMDs) and their variants. This is primarily a research-phase material studied for its electronic and mechanical properties, particularly in contexts where layered two-dimensional or quasi-2D behavior is desirable. The material's multi-metal composition differentiates it from binary TMDs (like MoS₂ or WSe₂) and positions it as a candidate for tuning band structure and carrier transport in next-generation electronic and optoelectronic devices.
