Tungsten diselenide is another layered transition metal dichalcogenide. Like more of the other TMDCs, it is a semiconductor with a band gap in the infrared region. In this article we review the Raman of WSe2 monolayer.
Like MoS2 and WS2, the lattice structure of WSe2 is also trigonal prismatic, while the lattice constant is 3.28 Å. The band gap of WSe2 is around 1eV.
