Abstract

The coordination complex WS3L2 (where L = S2CN(CH2CH3)2 ) can be used to deposit tungsten disulfide (WS2) thin films by aerosol-assisted chemical vapour deposition (AACVD). When WS3L2 is used in conjunction with the previ-ously reported precursor, MoL4 which produces molybdenum disulfide (MoS2) by AACVD, alloyed thin films of the type Mo1-xWxS2 are produced. The W/Mo ratio can be controlled by chang-ing the relative concentrations of precursors in the carrier aerosol, allowing straightforward manipulation of the optical properties of the material and exquisite control of the final film composition.
