In this study, we synthesized Mo(0.9)Wa(0.1)Te(2) nanobelts on the SiO2/Si substrates without using catalyst by a facile chemical vapour deposition method. Through detailed structural and compositional characterizations, we found that Mo(0.9)Wa(0.1)Te(2) nanobelts have a thickness of similar to 50 nm with a width-to-thickness ratio of 3-5 and a length up to tens of mu m. Besides, the grown nanobelts have a monoclinic structure with a growth direction of [010] and the {001} belt surface. Moreover, a vapour-solid growth mechanism is proposed to explain the growth of Mo(0.9)Wa(0.1)Te(2) nanobelts. This study demonstrated a simple synthesis method for the growth of single crystalline MoxW1-xTe2 nanomaterials, which is significant for the development of MoxW1-xTe2-based electronic and spintronic devices.
