Tungsten Selenide Sheet

Tungsten Selenide Sheet (WSe₂) is a layered transition metal dichalcogenide with semiconducting properties, notable for its tunable bandgap and strong light–matter interactions. The sheet form enables integration into optoelectronic devices, photovoltaic cells, and flexible electronic systems. Industries in electronics, photonics, and energy research use WSe₂ sheets for high-mobility transistors, photodetectors, and solar energy harvesting. Specific applications include field-effect transistors, flexible photodetector arrays, and absorber layers in next-generation solar cells. In research, WSe₂ sheets are central to studies on valleytronics, exciton dynamics, and two-dimensional heterostructure engineering. Their ability to function as both a semiconductor and a flexible layered material ensures vital importance in future optoelectronic and quantum device technologies.
