Abstract (italic typeface) Multi-walled carbon nanotubes (MWCNTs) array of about 40 nm in diameter and 500 to 1300 nm in length was directly grown on Au interdigitated electrodes by radio frequency plasma-enhanced chemical vapor deposition (RF-PECVD). The growth catalyst of Ni_3C-Ni at the tip of the MWCNTs array was observed by transmission electron microscope (TEM) and selected area electron diffraction (SAED). The sensing properties of MWCNTs arrays to NO_2, H_2S, CH_3SH and C_8H_10 were investigated at operating temperature from 100 to 250 oC. The resistance change to sulfur gases was higher than NO_2 and C_8H_10. It was suggested that Ni at the tip was sulfidized to be Ni_xS in sulfur gas and that the p-n junction was formed at the interface between p-type MWCNTs and n-type Ni_xS.
