Fabrication of patterned one‐dimensional (1D) nanostructures was recognized as the key process for the construction of functional display devices. In current investigation, we put forward the large‐scale and uniform growth of patterned 3 C ‐SiC nanowire arrays assisted by the patterned Au catalysts on SiC wafer substrate. The as‐fabricated SiC nanowires presented tapered configuration with a typical bamboo‐like body as well as clear and sharp tips. The as‐fabricated SiC nanoarray cathode has outstanding field emission (FE) characteristic that has a low turn‐on field ( E to ) of ~ 1.54 V/μm. The mechanism for their electron emission behaviors has been proposed.
