Tungsten Selenide, Pieces, 99.5%, 3 -6 mm

Tungsten selenide is a transition metal dichalcogenide (TMDC) used in the fabrication of 2D optoelectronic devices, including photodetectors and light-emitting diodes, due to its tunable bandgap.

Utilized as a p-type semiconductor in the development of next-generation field-effect transistors (FETs) and valleytronic components.

Tungsten selenide targets are used in physical vapor deposition processes to create thin films for solid-state lubrication and semiconductor research.

Produced in monolayer or few-layer forms via chemical vapor deposition or exfoliation for use in nanoscience and quantum physics research.
