Large area chemical vapor deposition and spectroscopic properties of bilayer WSe2

•The controllable synthesis of bilayer WSe2 films by chemical vapor deposition is achieved.•As-grown bilayer WSe2 exhibits good optical characteristics comparable to that of the exfoliated bilayers.•An asynchronous growth mode for bilayer WSe2 films is proposed. Large area preparation of WSe2 in dif...
