Monolayers of WxMo1−xS2 alloy heterostructure with in-plane composition variations

We report the fabrication of single-crystal monolayer Wx Mo 1−xS2 alloy triangles using chemical vapor deposition method. Raman and photoluminescence property are investigated in correlation to the composition. In the monolayer triangles, the photoluminescence peak shifts continuously from 687.4 nm...
