· Mo3 Se4 S2

Mo3Se4S2 is a layered transition metal chalcogenide semiconductor combining molybdenum with mixed selenium and sulfur anions. This is an experimental research material belonging to the family of two-dimensional and quasi-2D semiconductors currently under investigation for optoelectronic and energy conversion applications. The mixed-anion composition offers a tunable electronic bandgap and potential for enhanced performance compared to single-chalcogenide counterparts (such as MoS2), making it of interest for photocatalysis, photodetection, and emerging quantum device platforms where bandgap engineering and anisotropic transport properties are valuable.
