· W2 Se4

W₂Se₄ is a layered transition metal diselenide semiconductor compound belonging to the family of tungsten chalcogenides, which are studied for their unique electronic and optoelectronic properties. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in next-generation electronic devices, photovoltaics, and sensing systems where its semiconductor bandgap and crystal structure could offer advantages in thin-film or 2D device architectures.
