Single-phase (Hf_0.84Ta_0.16)C solid solution nanowires growth via catalyst-assisted chemical vapor deposition

Fabricating one-dimensional (1D) ceramic nanostructure with superior performance is an important approach to broaden their applications. In this paper, the synthesis of single-phase (Hf_0.84Ta_0.16)C solid solution nanowires via catalyst-assisted chemical vapor deposition was proposed for the first time. The [0 1 1̄] growth direction of (Hf_0.84Ta_0.16)C solid solution nanowires was discussed in detail and its corresponding growth mechanism was identified to be top-type vapor–liquid–solid mechanism. More impressively, our work could widen the application ranges of ceramic nanowires and propose the new thinking of fabricating ultrahigh melting point nanostructure.
