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 Mo_1-xW_xS₂ 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.
