Résumé

In this paper, we demonstrate a facile route to synthesize a continuous film of WS2 deposited by a combination of aerosol-assisted chemical vapor deposition (AACVD) with H2 free atmospheric pressure CVD technique. This synthesis strategy allows us a direct integration of the sensing material onto the sensor transducer with high growth yield and uniform coverage. SEM and Raman spectroscopy were used to investigate the morphology and composition of the grown material. The performance of WS2 sensor in the detection of H2S has been studied and results show that the synthesized material behaves as a p-type semiconductor with high sensitivity towards H2S at sub-ppm level.
