MoWSe2 monolayers consist of two Se atomic layers and a sandwiched metal (Mo/W) atom layer. The monolayer of MoWSe2 shows alternating atomic arrangement of Mo and Se sites in the hexagonal rings, with the Mo atoms partially and randomly substituted by W atoms compared to MoSe2. Like graphite, its interlayers are bound by weak van der Waals.
